Gamma Vibrational Bands and Chiral Doublet Bands in A≈100 Neutronrich Nuclei

    Graphical Abstract
    • Abstract
  • The level structures of neutronrich 105Mo, 106Mo, 108Mo and 110Ru nuclei in A ≈ 100 region have been carefully investigated by coincidence measurements of the prompt γrays populated in the spontaneous fission of 252Cf with the Gammasphere detector array. In 105Mo, onephonon K=9/2 and twophonon K=13/2 γvibrational bands have been identified. In 108Mo, onephonon γvibrational band is expanded and twophonon γvibrational 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 γvibrational bands. The characteristics for these γvibrational bands and chiral doublet bands have been discussed.
