主　　题：chiral doublet bands 98Tc particle rotor model 

摘      要：The candidate chiral doublet bands in 98 Tc with configuration πg9/2νh11/2 are studied the- oretically for the first time via the triaxial particle rotor model. The main properties of the doublet bands including the energy spectra and electromagnetic transitions are calculated for different triaxiality parameter γ, and the data in 98Tc can be well described by the calculations with γ = 38°. Based on the analysis of angular momentum components, it is found that the chiral rotational geometry in 98Tc deviates from the ideal chiral picture.
