Abstract
Two distinct sets of chiral-partner bands have been identified in the nucleus Ce. They constitute a multiple chiral doublet (MD), a phenomenon predicted by relativistic mean field (RMF) calculations and observed experimentally here for the first time. The properties of these chiral bands are in good agreement with results of calculations based on a combination of the constrained triaxial RMF theory and the particle-rotor model.
