摘要：

We discuss the role of deformation of the target nucleus in the fusion reaction of the C-15+Th-232 system at energies around the Coulomb barrier, in which C-15 is a well-known one-neutron halo nucleus. To this end, we construct the potential between C-15 and Th-232 with the double folding procedure, assuming that the projectile nucleus is composed of the core nucleus, C-14, and a valence neutron. In addition, we also take into account the coupling to the one-neutron transfer process to the C-14+Th-233 configuration. We show that such calculation simultaneously reproduces the fusion cross sections for the C-14+Th-232 and the C-15+Th-232 systems, implying an important role of the transfer coupling in fusion of neutron-rich nuclei.
