摘要：

Neutron capture cross sections have been calculated in nuclei near the N = 82 neutron shell-closure. These nuclei are of astrophysical interest, participating in the s-process and the p-process. A semimicroscopic optical model has been used with the potential being obtained through folding the target density with the DDM3Y nucleon-nucleon interaction. Theoretical density values have been calculated using the relativistic mean-field approach. The calculated cross sections, as a function of neutron energy, agree reasonably well with experimental measurements. Maxwellian-averaged cross sections, important for astrophysical processes, have been calculated.
