Özet

We have determined the most appropriate Hamiltonian that is needed for present calculations of nuclei about the A \cong 80 region by the view of Interacting Boson Model-2 (IBM-2). After obtaining the best Hamiltonian parameters, level energies and B(E2) probabilities of some transitions in 88,90Kr nuclei were estimated. Results are compared with previous experimental and theoretical data and it is observed that they are in good agreement. Finally, R1 = \frac{B(E2;41 \to 21)}{B(E2;21 \to 01)}, R2 = \frac{B(E2;22 \to 21)}{B(E2;21 \to 01)}, \ R3 = \frac{B(E2;02 \to 21)}{B(E2;21 \to 01)}, R4 = \frac{{B(E2;22 \to 01)}{B(E2;22 \to 21)}, R5 = \frac{B(E2;31 \to 21)}{B(E2;31 \to 41)}, R6 = \frac{B(E2;42 \to 41)}{B(E2;42 \to 22)} and R7 = \frac{B(E2;41 \to 21)}{B(E2;22 \to 21)} ratios are compared with the values of dynamic symmetry limits.

Abstract

We have determined the most appropriate Hamiltonian that is needed for present calculations of nuclei about the A \cong 80 region by the view of Interacting Boson Model-2 (IBM-2). After obtaining the best Hamiltonian parameters, level energies and B(E2) probabilities of some transitions in 88,90Kr nuclei were estimated. Results are compared with previous experimental and theoretical data and it is observed that they are in good agreement. Finally, R1 = \frac{B(E2;41 \to 21)}{B(E2;21 \to 01)}, R2 = \frac{B(E2;22 \to 21)}{B(E2;21 \to 01)}, \ R3 = \frac{B(E2;02 \to 21)}{B(E2;21 \to 01)}, R4 = \frac{{B(E2;22 \to 01)}{B(E2;22 \to 21)}, R5 = \frac{B(E2;31 \to 21)}{B(E2;31 \to 41)}, R6 = \frac{B(E2;42 \to 41)}{B(E2;42 \to 22)} and R7 = \frac{B(E2;41 \to 21)}{B(E2;22 \to 21)} ratios are compared with the values of dynamic symmetry limits.
