Title: N=38 sub-shell closure behavior of B(E2: 0{sub 1}{sup +} {yields} 2{sub 1}{sup +}) around 68Ni: Seniority and p-n interaction

Abstract

Some experimental data are analyzed to probe the sub-shell structure at N{approx_equal}40. It shows no clear evidence for magic number but is in agreement with a neutron sub-shell closure more probably located at N=38. The B(E2: 0{sub 1}{sup +} {yields} 2{sub 1}{sup +}) transition probability curves of even-even nuclei from 56Ni to 82Ge are confronted with results of calculations performed in an approximation of the generalized seniority and shown to fit with the N=38 sub-shell closure and a scenario involving p-n interaction accordingly to the Federmann and Pittel mechanism.
