Abstract
The 135La nucleus has been studied using the fusion-evaporation reaction 124Sn(17N,6n) induced by the 17N radioactive beam. The level scheme has been constructed from the γ-γ coincidence measurement with an array of 12 HPGe detectors, and the lifetimes of two previously known isomeric states has been deduced. The transitions and their intensities observed in the current work as well as the level scheme derived from them is in agreement with the results of a recently published work. However, our interpretation of the results differs significantly in terms of spin and parity assignments, thus solving various contradictions concerning the configurations of some of the bands discussed in the aforementioned work.
