Abstract：
The triaxial deformations of candidate nuclei of the chiral doublets bands in A～100 mass region are investigated in a microscopic and self-consistent triaxial relativistic mean field (RMF) approach. The convergence of results is examined. Based on the constraint RMF calculation with effective interaction PK1, the deformations of ground state in Rh, Ag and In isotopes have been obtained. Large triaxial deformation necessary for chiral doublets band is predicted in several nuclei.
