AbstractFollowing the observation of candidate chiral doublet bands in Br-78,Br-80, triaxial deformations with corresponding configurations in odd-odd bromine isotopes have been investigated using adiabatic and configuration-fixed constrained triaxial relativistic-mean-field calculations with an aim of finding the boundary of chirality in the chain of Br isotopes. Several minima with triaxial deformation and the proper particle-hole configuration were obtained in Br-74,Br-76,Br-78,Br-80,Br-82, where the chiral doublet bands have the possibility of occurrence. Furthermore, the possible existence of multiple chiral doublet (M chi D) bands is demonstrated in Br-74,Br-76,Br-78,Br-80,Br-82. Experiments to explore the chirality and M (chi) D properties of Br isotopes are conducted to verify the predictions.
