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

Highlights: • 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. - Abstract: 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.
