Testing the proposed one-and two- phonon -vibrational bands in ١٠٥Mo by the Interacting Boson- Fermion Model (IBFM)

The negative-parity levels in neutron-rich105Mo have been investigated by the theoretical model Interacting Boson-Fermion Model (IBFM). The two newly collective bands observed experimentally and suggested as the candidates for one-phonon and two-phonon double vibrational bands have been confirmed theoretically by the IBFM. The IBFM electromagnetic properties predicted gives more evidence for the existence of the multi-phonon bands in 105 Mo nucleus.
