Study of the structure of yrast bands of neutron-rich 114-124Pd isotopes

The projected shell model calculations have been carried out in the neutron-rich Pd114-124 isotopic mass chain. The results have been obtained for the deformation systematics of E(2(1)(+)) and E(4(1)(+))/ E(2(1)(+)) values, BCS subshell occupation numbers, yrast spectra, backbending phenomena, B(E2) transition probabilities and g-factors in these nuclei. The observed systematics of E(2(1)(+)) values and R-42 ratios in the Pd114-124 isotopic mass chain indicate that there is a decrease of collectivity as the neutron number increases from 68 to 78. The occurrence of backbending in these nuclei as well as the changes in the calculated B(E2) transition probabilities and g-factors predict that there are changes in the structure of yrast bands in these nuclei. These changes occur at the spin where there is crossing of g-band by 2-qp bands. The predicted backbendings and predicted values of B(E2) s and g-factors in some of the isotopes need to be confirmed experimentally.
