| Abstract: | Excited states of odd-odd nucleus ~(92)Nb and odd-A nucleus ~(93)Nb were populated in the 6 Li+ 89 Y 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 ~(92)Nb, and in addition two new transitions are added to the level scheme of ~(93)Nb. Using shell2 model calculations, the low-lying structure of 9 Nb is investigated and compared with the experimental results. |
