▼ Nuclei near N=90 and Z=64 have recently been suggested to be `
tetrahedral-magic'. One of the main signatures for
tetrahedral symmetry is a vanishing quadrupole moment in low-lying negative-parity bands, resulting in very weak or even vanishing E2 matrix elements. With N=90 and Z=62, the transitional nucleus 152Sm is a potential candidate for relatively stable
tetrahedral symmetry. Its structure was investigated using deuteron inelastic scattering with a 22 MeV polarized beam at the MP tandem Van de Graaff accelerator of the TU/LMU Munich. The scattered deuterons were momentum analyzed using the Q3D spectrometer. The experimental spectra obtained have allowed the extraction of high-quality differential cross-sections and analyzing powers for levels up to 1.8 MeV. The low-lying negative-parity bands are observed to be strongly populated and the angular distributions associated to their levels exhibit several structural features. The overall agreement is relatively good when considering strong intra-band E2 transitions, but further calculations must be performed to allow precise matrix element extraction. In particular, a simple population pathway test on the 1- state has demonstrated that calculations with vanishing E2 transitions in the negative-parity band are also capable of reproducing its experimental angular distributions. Therefore, the presence of
tetrahedral symmetry signature in 152Sm is not excluded.

▼ Packing problems are concerned with filling the space with copies of a certain object, so that the least amount of space stays unoccupied. The famous Kepler conjecture asserts that the cannonball packing of spheres is the most efficient packing achievable, and was recently formally proven by Hales. Dostert, Guzman, Oliveira Filho and Vallentin investigated the packing problem for other shapes. They focused on translative packings, in which all objects are oriented in the same direction. They proved several new upper bounds on translative packing densities of various Platonic and Archimedean solids. However, their results rely heavily on complex computer calculations to ensure they satisfy the conditions of a theorem. In this thesis, proof assistant Coq is used to formally verify these conditions. An introduction to Coq is provided, aimed at the working mathematician. Then, the theorems required for the proof are developed. Several results from multivariate calculus and convexity were required for the proof, but not available in Coq. The proof also requires a large amount of floating point calculations. A method is developed to efficiently perform floating point calculations on a large scale in Coq. Using the developed techniques, the improved upper bound of Dostert et al. on the translative packing density of the truncated tetrahedron is formally verified. These techniques can be reused to formally verify the other improved upper bounds of Dostert et al.

▼ Le travail présenté dans ce manuscrit regroupe deux études de spectroscopie γ. La première concerne les isomères des noyaux de néodyme autour de N=82. Ces noyaux, lorsqu’ils sont étudiés par des modèles de type Cranked-Nilsson-Strutinsky, présentent des états énergétiquement favorisés. Ils sont autant de candidats pour la recherche d’isomères de spin. Expérimentalement, un certain nombre d’états isomériques ont déjà été observés dans les noyaux de 138,139,140Nd sur lesquels porte cette étude. Afin de mieux caractériser ces états, une expérience a été menée en août 2009 à Jyväskylä auprès de l’ensemble de détection JUROGAM-RITU-GREAT. La réaction de fusion-évaporation 48Ca + 76Zr 144Nd* réalisée avec une cible mince a permis de produire majoritairement les noyaux 139,140Nd. Les noyaux produits, transportés au plan focal par le spectromètre RITU, sont implantés et le rayonnement émis par la décroissance des isomères est ensuite recueilli par l’ensemble de détection GREAT. Nous développerons l’analyse complète de cette expérience et nous montrerons les résultats émergents. Nous avons, par exemple, pu montrer l’alimentation du niveau 20+ de 140Nd ainsi que le placement énergétique du niveau isomérique du noyau 139Nd. La deuxième partie de ce travail s’articule autour de la recherche de la symétrie tétraédrique dans le noyau 156Gd. Cela a consisté à la fois en un travail de spectroscopie γ des bandes de parité positive de ce noyau, laquelle a fait émerger un certain nombre de nouvelles transitions. Le deuxième volet de cette étude consistait à simuler dans l’environnement ROOT - GEANT4 le seuil d’observation des signaux faibles avec le détecteur de rayonnements γ de nouvelle génération AGATA
Major part of this work is about the realization and complete analysis of an experiment for study of isomeric states in 138,139,140Nd nuclei. This was performed at Jyväskylä laboratory (Finland) using a fusion-evaporation reaction with 48Ca beam on a thin 96Zr target. Experimental setup consisted in the target position gamma ray detector JUROGAM II which was coupled with the RITU recoil separator and the GREAT focal plane detector array. This particularly well adapted setup permit to manage γ spectroscopy of the interest nuclei around isomeric states. Indeed, we used prompt-delayed matrix to separate rays that come onto isomeric states and these who decay from them. Then, correlations between the two components permit to establish feeding transitions of isomeric states. During this experiment, a new isomeric state was also highlighted in 139Nd with spin 23/2+, which was predicted and interpreted in Cranked-Nilsson-Strutinsky calculation. Finally, very clean time spectra allow to determine precisely life-time of four states in four nuclei. This PhD is also made of a part of analyze on experimental search for fingerprints of tetrahedral symmetry in 156Gd using high fold gamma ray spectroscopy. Thanks to a large number of triple coincidence events, we managed a detailed spectroscopy of this nucleus. Particularly, we found out 13 new…

▼ In a quest to design novel deployable structures, flexible polyhedra provide interesting
insights. This work follows the discovery of flexible polyhedra and aims to make flexible
polyhedra more useful.
The dissertation describes how flexible polyhedra can be made. The flexible polyhedra
first considered in this dissertation have a rotational degree of freedom. The range of this
rotational movement is measured and maximised in this work by numerical maximisation.
All polyhedra are established computationally: an iterative solution method is used to find
vertex coordinates; several clash detecting methods are described to define whether each
rotational position of a flexible polyhedron is physically possible; then a range of motion is
defined between occurrences of clashes at the two ends; finally, an optimisation tool is used
to maximise the range of motion.
By using these tools, the range of motion of two types of simplest flexible polyhedra
are maximised. The first type is a series of flexible polyhedra generalised from the Steffen
flexible polyhedron. The range of motion of this type is improved to double that of Steffen’s
original, from 27° to 59°. Another type of flexible polyhedron is expanded from a model
provided by Tachi. Based on the understanding of Steffen’s flexible polyhedron, optimisation
parameters are carefully given. This new type has achieved a wider range of motion, so now
the range of motion of flexible polyhedron is tripled to 80°.
After enlarging the range of motion of the degree of freedom in the 1-dof systems, the
dissertation found multiple degrees of freedom in one polyhedron. The multiple mechanisms
can be even repetitive, so that an n-dof polyhedron is found. A polyhedron of two degrees
of freedom is first presented. Then, a unit cell for any number of mechanisms is found.
As a repetitive structure, a 3-dof polyhedron is presented. Finally, this work presents the
possibility of configuring a flexible polyhedral torus and a closed polyhedral surface that is
able to flex without the need to stop.

▼ Les symétries géométriques jouent un rôle important dans la compréhension de la stabilité de tout système physique. En structure nucléaire, elles sont reliées à la forme du champ moyen utilisé pour décrire les propriétés des noyaux atomiques. Dans le cadre de cette thèse, nous avons utilisé les prédictions obtenues avec l'aide du Hamiltonien du champ moyen nucléaire avec le potentiel de Woods-Saxon Universel pour étudier les effets des symétries dites de « Haut-Rang ». Ces symétries ponctuelles mènent à des dégénérescences des états nucléaires d’ordre 4. Il est prédit que la symétrie tétraédrique influence la stabilité des noyaux proches des nombres magiques tétraédriques [Z,N]=[32,40,56,64,70,90-94,136]. Nous avons sélectionné la région des Terres-Rares proche du noyau doublement magique tétraédrique 154Gd pour notre étude. Dans cette région, il existe des structures de parité négative qui sont mal comprises. Or la symétrie tétraédrique, en tant que déformation octupolaire non-axiale, brise la symétrie par réflexion et doit produire des états de parité négative. Après une étude systématique des propriétés expérimentales des noyaux de la région, nous avons sélectionné le 156Gd comme objet de notre étude des modes d’excitation octupolaire. Nous avons utilisé les probabilités réduites de transition gamma pour discerner ces différents modes. Pour atteindre cet objectif, nous avons réalisé trois expériences de spectroscopie gamma à l’ILL de Grenoble avec les détecteurs EXILL et GAMS afin de mesurer les durées de vie et les intensités des transitions gamma des états candidats. L'analyse de nos résultats montre que notamment la forme tétraédrique aide à comprendre les probabilités des transitions dipolaires. Ce résultat ouvre de nouvelles perspectives expérimentales et théoriques.
Geometrical symmetries play an important role in the understanding of all physical systems. In nuclear structure they are linked to the shape of the mean-field used to describe the atomic nuclei properties. In the framework of this thesis, we have used the predictions obtained with the help of the nuclear mean-field Hamiltonian with the Universal Woods-Saxon potential to study the effects of the so-called “High-Rank” symmetries. These point-group symmetries lead to a nuclear state degeneracy of the order of 4. It is predicted that the tetrahedral symmetry affects the stability of nuclei close to the tetrahedral magic numbers [Z,N]=[32,40,56,64,70,90-94,136]. We have selected the Rare-Earth region close to the tetrahedral doubly magic nucleus 154Gd for our study. In this region, there exists negative parity structures poorly understood. Yet the tetrahedral symmetry, as related to a non-axial octupole deformation, breaks the reflection symmetry and leads to the negative parity states. Following a systematics of experimental properties of the nuclei in this region, we have selected 156Gd as the object of our study for the octupole excitation modes. We have used the reduced transitions probabilities to discriminate between these modes. To achieve…
