Spectroscopic Properties and Collectivity Beyond $^{132}$Sn

Résumé

Recent shell-model advances in the mass region above the doubly closed core 132Sn are reported in the present work. Using an effective interaction based on the N3LO potential, the low-lying spectra, E2 and M1 transition strengths are calculated for the following nuclei: 134,136,138Te, 136,138,140Xe, 138,140,142Ba, 140,142,144Ce and 142,144,146Nd. We focus in the discussion on the collectivity in the N = 86 isotones characterized by development of triaxial γ bands.
