✦ Synopsis

We have studied the coexistence of cluster structure and mean-field-type structure in 40 Ca using Antisymmetrized Molecular Dynamics (AMD) + Generator Coordinate Method (GCM). By energy variation with constraint, we calculated GCM basis wave functions. Superposing cluster structure wave functions and mean-field-type structure wave function, we found that α-36 Ar and 12 C-28 Si cluster structure are important components of normal-deformed (ND) band of 40 Ca and that of superdeformed (SD) band of 40 Ca, respectively.
