Seniority scenario for the 68-72Zn and 66-68Ni B(E2) difference
Isabelle Deloncle, Brigitte Roussiere
Abstract
The very simple product of the number of particles by the number of holes appearing in the expression of the reduced B(E2: 0+1 -> 2+1) (B(E2)) transition probability of even-even nuclei obtained from the extension of the seniority scheme is used to analyze in a same time the experimental B(E2) values of 56-68 Ni and those of 62-72Zn. The evolution of these B(E2) values with neutron number fits in with a scenario involving p-n interaction.
