Novel features of nuclear structure of Z=46Pd isotopes

The spectral features of N = 54-70, Z = 46Pd isotopes are presented through empirical studies. The unique behavior of Pd isotopes in the simultaneous increase of the quadrupole deformation beta and the triaxiality parameter gamma is illustrated, and the roles of valence neutrons and valence protons are highlighted. The n = 2 phonon triplet structure of Pd isotopes is studied in detail. The level spectra are well reproduced in the Interacting Boson Model. The IBM predicted interband E2 transition ratios are compared with the data. (c) 2022 Published by Elsevier B.V.
