B(E2) value of even-even 108-112Pd isotopes by interacting boson model-1

  • 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-even 108-112Pd 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 rst 4+ and the rst 2+ excited states, R4/2, is also studied for the classi cation 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. The 108-112Pd isotopes show the O(6) symmetry.

B(E2) value of even-even 108-112Pd isotopes by interacting boson model-1

Abstract: 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-even 108-112Pd 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 rst 4+ and the rst 2+ excited states, R4/2, is also studied for the classi cation 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. The 108-112Pd isotopes show the O(6) symmetry.
