Description
We calculate the low-lying B(E2,0g.s.+→2f+) distribution of strength in 68Ni and other nickel isotopes using several theoretical approaches. We find that in 68Ni the calculated B(E2) transition to the first 2+ state exhausts only a fraction of the low-lying B(E2) strength, while the remainder of the low-lying strength is mainly collected in the group of states lying above 4 MeV. This fragmentation is sensitive to the size of the N=40 gap. We argue that the small experimental B(E2) value to the first 2+ state is not a strong evidence for the double-magic character of 68Ni
