Effects of nonlocality of nuclear potentials on direct capture reactions

Calculations of the direct radiative capture reactions are made for the Ca48(n,γ)Ca49, Li7(n,γ)Li8, and C12(p,γ)N13 reactions with the Perey-Buck-type nonlocal potentials using a potential model. Our results reproduce the experimental data reasonably well. From comparisons to results obtained by using local potentials, it is found that the cross sections of direct capture reactions may change by around 25% due to the nonlocality of nuclear potentials.
