Backbending andγvibrations

J. Kvasil, R. G. Nazmitdinov
2004 Physical Review C  
We propose that the backbending phenomenon can be explained as a result of the disappearance of collective gamma-vibrational mode in the rotating frame. Using a cranking+random phase approximation approach for the modified Nilsson potential + monopole pairing forces, we show that this mechanism is responsible for the backbending in ^156Dy, ^158Er and obtain a good agreement between theoretical and experimental results.
