Collective properties of neutron-rich Ru, Pd, and Cd isotopes

Abstract

Collective properties of neutron-rich Ru, Pd, and Cd isotopes are reviewed, combining the original results from the IGISOL s-decay experiments with recent experimental and theoretical progress. The transitional nature of Ru and Pd nuclei is discussed via the low-lying level systematics, including the low-lying 0+ states. Although the role of an anharmonic quadrupole vibrator in Cd nuclei was recently questioned, level systematics for the three-phonon quintuplet in 116,118,120Cd are presented, and an outlook of the spectroscopic methods for the level lifetime or B(E2) values is given.
