Measurement of neutron capture cross sections and neutron capture gamma-ray spectra of 93Nb, 103Rh and 115In in keV-energy region

•The neutron capture cross sections of 93Nb, 103Rh and 115In were measured.•The neutron capture cross sections were determined with uncertainties less than 5%.•The neutron capture γ-ray spectra were derived from the pulse-height spectra.

The neutron capture cross sections of 93Nb, 103Rh and 115In were measured by the time-of-flight method in the energy region from 15 keV to 100 keV. A pulse-height weighting technique was employed to derive the neutron capture cross sections. The neutron capture γ-ray spectra were derived by unfolding the pulse-height spectra with the detector response functions.
