Abstract:The (t, p) reactions leading to 38,40,42Ar and 42Ca have been used to study the 0+ level spectrum near the N = 20 neutron closed shell. The Ar isotopes show a significant reduction and fragmentation of the L = 0 (t, p) strength relative to Ca. A major change in the structure of the 0+ levels thus takes place between Ca and Ar.
