英文摘要	We provide a microscopic description of the fusion reactions between Ca-40,Ca-48 and Ni-78. The internuclear potentials are obtained using the density-constrained (DC) time-dependent Hartree-Fock (TDHF) approach and fusion cross sections are calculated via the incoming wave boundary condition method. By performing DCTDHF calculations at several selected incident energies, the internuclear potentials for both systems are obtained and the energy-dependence of fusion barrier are revealed. The influence of tensor force on internuclear potentials of Ca-48+Ni-78 is more obvious than those of Ca-40+Ni-78. By comparing the calculated fusion cross sections between Ca-40+Ni-78 and Ca-48+Ni-78, an interesting enhancement of subbarrier fusion cross sections for the former system is found, which can be explained by the narrow width of internuclear potential for Ca-40+Ni-78 while the barrier heights and positions are very close to each other. The tensor force suppresses the subbarrier fusion cross sections of both two systems.
