Research Of High Spin States In Neutron-Rich ～(104,106,108) Mo Nuclei

High spin states in neutron-rich ~{104,106,108}Mo nuclei have been studied by measuring the prompt γ-rays emitted after their formation in the spontaneous fission of 252Cf. The measurement was carried out at the Lawrence Berkeley National Laboratory. Prompt γ-γ-γcoincidence studies were performed with the Gammasphere detector array consisting of 102 Compton-suppressed Ge detectors. A three-dimensional histogram (cube) of 5.7×1011 coincidence events was constructed. The coincidence data were analysed with the Radware software package.The new level schemes of neutron-rich ~{104,106,108}Mo based on our new data are presented. In 104Mo,a total of 10 new levels and 14 new transitions were identified. In 106Mo, a total of 31 new levels and 68 new transitions were identified with spin up to 16 ?, and a total of 8 rotational bands, among which, four of them are new ones, have been observed. In 108Mo, a total of 23 new levels and 43 new transitions were identified with spin up to 16 ?.A systematic study of the behavior of the collective bands of the three neutron-rich even Mo isotopes is performed. The characteristics of the collective bands and the possible configuration for the quasi-particle bands in the three neutron-rich even Mo isotopes are discussed.
