Super deformation to maximum triaxiality in A = 100 - 112; superdeformation, chiral bands and wobbling motion

The spectral features of N = 54-70, Z=46 Pd isotopes are presented through empirical studies. The unique behavior of Pd isotopes in the simultaneous increase of the quadrupole deformation β and the triaxiality parameter γ 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.
