Dinuclear system in diabatic two-center shell model approach

Diabatic potentials as a function of the elongation and neck parameter for various symmetric heavy-ion systems are studied within the generalized two-center shell model. In the calculations the maximum symmetry method is applied. The diabatic potentials show hindrances for the motion to a smaller relative distance and for the growth of the neck. They are similar to nucleus-nucleus potentials used in the dinuclear system model of fusion which is able to describe the experimental data. The dependence of the diabatic potential on temperature and mass asymmetry is discussed.
