Study of the Nb93(nres, γ)Nb94 Reaction

The high-energy γ-ray spectra following capture in one s-wave and three p-wave resonances in Nb have been observed with a Ge(Li) detector. The low-lying energy levels of Nb94 inferred from the data are consistent with those previously reported on the basis of (d, p) and low-energy (n, γ) data. From the observed decay properties of the intial states, the spin assignments for the resonances are inferred to be Jrπ=5-(35.8 eV), 4+(119.2 eV), 4- or …
