Abstract:Sub-barrier fusion excitation functions of35,37Cl+58,64Ni have been measured. They are discussed in comparison to similar data of34,36S+58,64Ni with the aim of revealing the influence of coupled proton transfer channels. Using the simplified coupled channel code CCFUS, differences in the effects of inelastic channels are eliminated in an approximative manner to stress the differences in the effects of transfer channels. Signatures of positiveQ-value transfer channels coupled to fusion are clearly identified.
