Title: Chirality, wobbling and oblate rotation

Speaker:  C. M. Petrache, Full professor at the University Paris Saclay, France

Abstract:

The breaking of symmetries in quantum systems is one of the key issues in nuclear physics. In particular, the spontaneous symmetry breaking in rotating nuclei leads to exotic collective modes, like the chiral and wobbling motions, which have been intensively studied in recent years. These recent experimental results and their interpretation will be presented. Another topic of current interest is the existence of collective oblate shapes and their type of motion. Solid evidence of bands built on oblate shapes close to the ground state in 119Cs, and at very high spin in 137Nd has been recently published. These experimental results and their interpretation will be discussed.
