摘要：

Neutron-capture cross sections in the energy range of 0.01-10 MeV for Sm-146,Sm-148,Sm-150,Sm-152 nuclei were calculated using the gamma-ray strength and level density functions extracted from the Oslo-type experiments. The uncertainties in the cross-section values were determined using a Monte Carlo method. For the Sm-148,Sm-150,Sm-152 isotopes, the calculated cross sections are in a good agreement with the existing experimental data and for the Sm-146 nucleus, an experimental (n, gamma) cross section is reported for the first time. The results are compared with the ENDF, EAF, and TENDL evaluations. Maxwellian-averaged cross sections were also calculated using the same input gamma SF and LD functions.
