Niobium(Nb) is used as one of material elements of Nuclear Reactor. In order to improve the accuracy of cross sections, measuements of neutron capture and total cross sections of ⁹³Nb were perfomed at ANNRI of MLF in J-PARC via Germanium detecters and Li-glass detectors. The resonance parameters of ⁹³Nb below 400 eV were derived from the measuements results by using resonance analysis code, REFIT.
