Low-lying states of 92,93Nb excited in the reactions induced by the weakly-bound nucleus 6Li near the Coulomb barrier

Excited states of odd-odd nucleus Nb-92 and odd-A nucleus Nb-93 were populated in the Li-6+ Y-89 reaction with an incident energy of 34 MeV. The processes that produce (92,93) Nb and can be measured by a combination of light charged particle and gamma ray measurements are discussed. Twenty new transitions are observed and eight new levels are constructed in Nb-92, and in addition two new transitions are added to the level scheme of Nb-93. Using shell model calculations, the low-lying structure of Nb-92 is investigated and compared with the experimental results.
