Abstract

The results obtained from electron and in-beam spectroscopy experiments reveal that the 44 S nucleus is located in a transitional region between the spherical 48 Ca and the oblate 42 Si. The comparison of the results with Large Scale Shell Model calculations points towards prolate-spherical shape coexistence where the ground state becomes the intruder configuration due to quadrupole excitations across the Z = 14 and N = 28 shell gaps.

“…The main focus lies on the competition of isospin T = 0 and T = 1 states in the hitherto heaviest odd-odd N = Z nuclei with known excited states: 82 Nb and 86 Tc [25,26,27].…”

Progress in the conceptual design of future gamma-tracking arrays with imaging capabilities. Lifetime measurement in neutron-rich nuclei in the region of the double magic Ni with the AGATA demonstrator

“…Neutron-rich nuclei are as well of extreme relevance for the stellar nucleosynthesis. In particular, nuclei in the intermediate mass region, close to 78 Ni, play an important role in the nucleosynthesis via r-process.…”

“…This re-ordering of the shell structure was suggested to be originated by deformation.

“…Different regions of the nuclear chart where nuclei have large neutron excess, have been studied in the context of the shell evolution as the p-shell and sd-shell [131]. In this work, we are interested in the neutron-rich isotopes around the double magic nucleus 78 Ni involving the fp-shell.…”
