Transition from Electric Rotation to Chiral Mode in 135Nd

With the inputs from the relativistic mean field approach, the observed energy spectra and electromagnetic properties are well reproduced for the yrast band of odd-A nucleus 135Nd by the particle rotor model. Based on the analysis of the angular momentum components, it is further illustrated that this yrast band contains two stages of rotational mode, i.e., the electric rotation for low-spin region and chiral mode for high-spin region.
