Abstract

The sub-barrier capture (fusion) reactions ³²S+^90,94,96Zr, ³⁶S+^90,96Zr, ⁴⁰Ca+^90,94,96Zr, and ⁴⁸Ca+^90,96Zr with positive and negative Q-values for neutron transfer are studied within the quantum diffusion approach and the universal fusion function representation. For these systems, the s-wave capture probabilities are extracted from the experimental excitation functions and are also analyzed. Different effects of the positive Q_xn-value neutron transfer in the fusion enhancement are revealed in the relatively close reactions ³²S+^94,96Zr and ⁴⁰Ca+^94,96Zr.
