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), showing wobbling 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 displayedin these two TW candidates will be introduced.
