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.
