Abstract：
To understand the microscopic origin of the signature inversion in the yrast positive-parity bands of doubly odd Rb nuclei, as an example, we performed calculations using the projected shell model (PSM) to describe the energy spectra in ⁸²Rb. It can be seen that the main features are reproduced in the calculations. This analysis shows clearly that the signature splitting and especially the signature inversion are reproduced only by a varying γ deformation with increasing spin.
