Neutron-capture cross sections in the energy range of 0.01–10 MeV for ${}_{146, 148, 150, 152}{Sm}$ nuclei were calculated using the $γ$ -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 ${}_{148, 150, 152}{Sm}$ isotopes, the calculated cross sections are in a good agreement with the existing experimental data and for the ${}_{146}{Sm}$ nucleus, an experimental $(n, γ)$ 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 $γ SF$ and LD functions.
