Odd Features of Some Odd-Odd Prolate Spheroidal Nuclei
We address the theoretical interpretation of rotational bands and low-lying states in odd-odd prolate fission-products Nb and La nuclei, which are characteristic of shape transition and coexistence. Our Projected Shell Model (PSM), Total Routhian Surface (TRS) and Potential Energy Surface (PES) calculations were applied to the odd-odd 104,106Nb. Results for 142La show theoretically a high-spin state as band-head in the case of both odd neutron and proton in K = 1/2 states.
