STUDY OF BE ISOTOPES BASED ON THE GENERALIZED TWO-CENTER CLUSTER MODEL

A generalized two-center cluster model (GTCM), including various partitions of the valence nucleons around two a-cores, is proposed for studies on the exotic cluster structures of Be isotopes. This model is applied to the "Be=a + 01 + 271 and the ' 2 B e = a + ~ + 4 n systems. The adiabatic energy surfaces for a01 distances are calculated. It is found that this model naturally describes t.he formation of the molecular orbitals as well as that of asymptotic cluster states depending on their relative distance.
