摘　　要：The deformations and the corresponding configurations of the odd-odd As isotopes are investigated using the adiabatic and configuration-fixed constrained triaxial relativistic mean field(RMF)theory.Energy minima with triaxial deformations and high-j particle-hole configurations are obtained in 72,74,76,78,80As,where the chiral doublet bands are possible to appear.The existence of multiple chiral doublet(MχD)is demonstrated in 74,76,78As.Based on the calculated single-particle levels,we also find possible coexistence of chiral and pseudospin symmetries in the odd-odd As isotopes.
