  Radiative thermal neutron capture cross sections for nuclei participating in
s-process and p-process nucleosynthesis in and around $N=50$ closed neutron
shell have been calculated in statistical semi-microscopic Hauser-Feshbach
approach for the energy range of astrophysical interest. A folded optical model
potential is constructed utilizing the standard DDM3Y real nucleon-nucleon
interaction. The folding of the interaction with target radial matter
densities, obtained from the relativistic-mean-field approach, is done in
coordinate space using the spherical approximation. The standard nuclear
reaction code TALYS1.8 is used for cross-section calculation. The cross
sections are compared with experimental results and reasonable agreements are
found for almost all cases. Maxwellian-averaged cross sections (MACS) for the
nuclei are presented at a single thermal energy of 30 keV relevant to
s-process. We have also presented the MACS values over a range of energy from 5
to 100 keV for neutron magic nuclei with $(N=50)$.
