Résumé :

The Shell Model approach is nowadays one of the most powerful tools used in the theoretical nuclear structure studies, which enables a unified description of spectroscopy and decays of atomic nuclei. In this talk, after a short introduction concerning the shell model itself, we will discuss recent progress in constraining the effective interactions in enlarged valence spaces and the resulting studies in different parts of the nuclear chart. In particular, we will present the shell model results around mass A \sim 95, discussing the origin of deformation in this region and structure of high-spin isomers. Then, we will adress the problem of shell quenching in Cadmium isotopes. The nuclear structure calculations relevant for double beta decays will be also presented. Finally, we will discuss recent progress in the half-life calculations for nuclei of astrophysical importance.
