One-hole states in double magic nuclei

We discuss the equation of motion = (E/sub B/ - E/sub 0/) in the subspace of states vertical-barpsi/sub B/> = summation /sub b/..cap alpha..a/sub b/0>, where vertical-barpsi/sub 0/> is the correlated ground state of a double magic nucleus. It is shown that this equation can be solved with high accuracy if some low-order correlation functions of the expS theory are known. Preliminary results are given for /sup 3/H and /sup 15/N for four different nucleon-nucleon interactions, i.e., the Reid-soft-core potential with and without the three-body correction of Blatt and McKellar, the Hamada-Johnston potential, and the de Toureill-Sprung supersoft-core potential. The connection with shell model states is discussed.
