Abstract: The level structures of neutronrich 105Mo, 106Mo, 108Mo and 110Ru nuclei in A ≈ 100 region have been carefully investigated by coincidence measurements of the prompt γrays populated in the spontaneous fission of 252Cf with the Gammasphere detector array. In 105Mo, onephonon K=9/2 and twophonon K=13/2 γvibrational bands have been identified. In 108Mo, onephonon γvibrational band is expanded and twophonon γvibrational band has been identified. Two similar sets of bands in 106Mo and 110Ru are observed to high spins, which have been proposed as the soft chiral γvibrational bands. The characteristics for these γvibrational bands and chiral doublet bands have been discussed.
