Abstract

Wobbling motion represents the quantized oscillations of the rotational axis of a rotating nucleus with triaxial shape about the space-fixed angular momentum vector [1].Transverse wobbling (TW), showingwobbling energy decreases with angular momentum, is a novel version thereof unique to triaxial nuclei [2]. Most of TW bands are identified in odd-proton nuclei. In this talk, I will first introduce what’s the TW, why it can form, how does its angular momentum behave, and then introduce how do we describe the newly observed TW bands in the odd-neutron nucleus 105Pd (Z=46, N=59) [3] and even-even nucleus 130Ba (Z=56, N=74) [4].Specific features displayed in these two TW candidates will be introduced.

Biography:

Qibo Chen is now a post-doctor in Technical University of Munich. He received his bachelor degree from Southwest University in 2010 and PhD degree from Peking University in 2015. From July 2015 to June 2017, he worked as a postdoctoral researcher at PKU and got the first PKU Boya post-doctor fellowship, and two China Postdoctoral Science Foundation programs (the first class General program and the Special program). From September 2017, he moved to TU Munich. His research interest is mainly focused on the exotic rotational modes of triaxially deformed nuclei, including the nuclear wobbling motion, nuclear chirality, and multi-chirality. He has published more than 40 papers in peer-review journals.
