本文用Perey-Buck型非定域势模型计算了$^{48}$Ca$（n，\gamma）^{49}$Ca，$^7$Li $（n，\gamma）^8$Li和$^{12}$C$（p，\gamma）^{13}$N反应的直接辐射俘获反应.我们的结果再现实验数据相当不错。通过与用定域势计算结果的比较，发现由于核势的非定域性，直接俘获反应的截面可能发生25%左右的变化。
Calculations of the direct radiative capture reactions are made for the $^{48}$Ca$(n,\gamma)^{49}$Ca, $^7$Li$(n,\gamma)^8$Li and $^{12}$C$(p,\gamma)^{13}$N reactions with the Perey-Buck type nonlocal potentials using a potential model. Our results reproduce the experimental data reasonably well. From comparisons with 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 nonlcality of nuclear potentials.
