摘 要: | This work studies the systematic reduced transition probabilities B(E2)↓, intrinsic quadrupole moments and deformation parameters of Pd isotopes with even neutrons from N =62 to 66. The downward reduced transition probabilities B(E2)↓from gamma transition 8^+to 6^+, 6^+ to 4^+, 4^+ to 2^+ and 2^+ to 0+states of even-even108 112Pd isotopes were calculated by the Interacting Boson Model(IBM-1) and compared with the available previous experimental results. The ratio of the excitation energies of the first 4+and the first 2+excited states, R4/2, is also studied for the classification of symmetry of these nuclei. Furthermore we have studied systematically the transition rate R = B(E2: L+ →(L 2)+)/B(E2 : 2+ →0+) of some of the low-lying quadrupole collective states in comparison with the available experimental data. The associated quadrupole moments and deformation parameters have been calculated. The results of this calculation are in good agreement with the corresponding available experimental data. The108 112Pd isotopes show the O(6) symmetry.
