Soft Chiral Vibrations In Mo-106

High-spin states in neutron-rich Mo-106 were investigated by detecting the prompt gamma-rays in the spontaneous fission of Cf-252 with Gammasphere. Several new bands are observed. Two sets of Delta I = 1 bands in Mo-106 are found to have all the characteristics of a new class of chiral vibrational doublets. Tilted axis cranking calculations support the chiral assignment and indicate that the chirality is generated by neutron h(11/2) particle and mixed d(5/2), g(7/2) hole coupled to the short and long axis, repectively.
