AbstractThe empirical coupled-channel (ECC) model and the universal fusion function (UFF) prescription are used to analyze the data of capture cross sections for reactions K-39 + Ta-181 and K-46 + Ta-181 reported recently by Wakhle et al. [Phys. Rev. C 97, 021602(R) (2018) ]. The results of the ECC model are in good agreement with the data of K-39 + Ta-181, while for K-46 + Ta-181 the predictions of the ECC model overestimate the above-barrier capture cross sections. Comparing the reduced data of these two reactions, it is found that the above-barrier cross sections of K-39 + Ta-181 are consistent with the UFF and are larger than those of K-46 + Ta-181. This implies that the capture cross sections of K-46 + Ta-181 are suppressed at energies above the Coulomb barrier. Furthermore, at sub-barrier energies, the reduced calculated capture cross sections of K-39 + Ta-181 are a little larger than those of K-46 + Ta-181, which is owing to the coupling to the positive Q-value two-neutron transfer channel.
