Quadrupole Collective Excitations in Medium Heavy Transitional Nuclei within a Selfconsistent Approach with Skyrme Forces

摘要

We present an attempt to describe collective quadrupole excitations in medium heavy transitional nuclei starting from HF-BCS approach with Skyrme SIII forces. The collective dynamics is treated through the Bohr Hamiltonian with mass parameters and moments of inertia calculated microscopically in the cranking approximation. Theoretical energy levels and B(E2) transition probabilities for ¹⁰²Zr, ¹⁰⁴Mo, ¹¹⁰Ru, ¹¹⁰Pd, ¹²⁴Xe and ¹²⁶Ba nuclei are compared with experiment.
