Abstract: In this paper, we present new spectroscopic information on 94Nb nucleus from the 93Nb(nth,2gamma) reaction. The intensities of the two-step gamma cascades in the compound nucleus 94Nb to the final levels with the excitation energy below 400 keV were derived from experimental spectra recorded at the PGAA facility of Centre for Energy Research (MTA EK), Budapest, Hungary. The intensities, energies of primary and secondary transitions of 216 energy-resolved cascades, as well as intermediate cascade levels, were determined. The part of the level scheme of 94Nb nucleus was obtained from the analysis of the intensity spectra of the strongest cascades. The results were compared to the existing data in the ENSDF database. We concluded that 27 primary transitions, 29 intermediate cascades levels as well as 183 secondary transitions can be recommended as new nuclear data.
