OSTI ID:6911419
The effects of nuclear structure on subbarrier fusion in some light and medium heavy systems are studied in a two-dimensional barrier penetration model. The low-lying intrinsic excitations are represented by surface harmonic vibrations whose parameters are determined to reproduce low-lying collective excitations. The intrinsic degrees of freedom are coupled to the relative motion of two nuclei through a proximity nuclear-nuclear potential which is a function of the closest distance between two surfaces on the nuclei. The author finds that this model is able to explain the enhancements in the subbarrier fusion observed in a variety of systems: /sup 16/O + /sup 18/O, /sup 16/O + /sup 16/O, /sup 46/Ti + /sup 90/Zr, /sup 93/Nb, /sup 50/Ti + /sup 90/Zr, /sup 93/Nb, /sup 81/Br + /sup 90/Zr, and /sup 64/Ni + /sup 58/Ni.
