Abstract

With the quantum diffusion approach the behavior of the capture cross-section is investigated in the reactions ^{92, 94}Mo + ^{92, 94}Mo , ¹⁰⁰Ru + ¹⁰⁰Ru , ¹⁰⁴Pd + ¹⁰⁴Pd , and ⁷⁸Kr + ¹¹²Sn at deep sub-barrier energies which are lower than the ground-state energies of the compound nuclei. Because the capture cross-section is the sum of the complete fusion and quasifission cross-sections, and the complete fusion cross-section is zero at these sub-barrier energies, one can study experimentally the unique quasifission process in these reactions after the capture.
