The neutron radiative capture measurements for enriched isotope Sm are performed at the neutron spectrometer of LNPh JINR by a gamma-rays multiplicity method using the multisectional 4p-detector “Romashka” placed on the 500 m flight path of the IBR-30 booster. The gamma-multiplicity spectra of resolved resonances were obtained in the energy range from 15 eV to 300 eV. The mean gamma-rays multiplicity was determined the energy, the average multiplicity, the spin and the radiative width for 91 resonances.
