Abstract

We present results from stopped beam rare isotope spectroscopic investigations at the GSI (RISING) experiment based on the detection of γ-ray transitions following the β decay of 94Pd. A comparison between the measured low-lying level scheme of 94Rh and the prediction from shell-model calculations reveals the important roles of the g7/2 and g 9/2 orbitals in explaining the structural features. The low values of the Gamow-Teller strengths B(GT) can be attributed to the influence of the neutron-proton interaction, which gives rise to an increased seniority mixing for the nuclear states, thereby leading to a fragmentation of the strength to several daughter levels. These results provide further strong indications that 94Pd resides in the middle of a structural transition region in the Pd isotopes as the N=Z line is approached. © 2012 American Physical Society.
