Abstract
In this paper, we present new spectroscopic information on Nb94 from the Nb93(nth,2γ) reaction. The intensities of the two-step gamma cascades in the compound nucleus Nb94 to the final levels, with excitation energies 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 Nb94 was obtained from analyzing 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.
