Abstract

Utilizing the Risø bent crystal spectrometer, 47 transitions have been observed from 54 keV to ≈ 1 MeV from the reaction Nb⁹³(n,γ)Nb⁹⁴. These transitions determine the following levels in Nb⁹⁴ (energy in keV, spin-parity in parentheses): G.S. (6⁺, ≈ 40.7 (3⁺), 58.724 (4⁺), 78.675 (7⁺), 113.404 (5+), 314.64 (5⁺), ≈ 334 (2⁺) and 640.5 (5⁺). The 315 keV and 641 keV states probably correspond primarily to the J = 3 2 state of the three neutron configuration coupling to the g _{9 2} proton configuration. The other six states result primarily from the coupling of the J = 5 2 state of the three neutron configuration and the g _{9 2} proton configuration. Energies of the levels and transition probability ratios are consistent with this interpretation.
