Abstract: | Theg factors of the first excited 2+ levels in the neutron-rich nuclei102Mo and104Mo have been studied through the measurement of the perturbed angular correlations for theγ-γ cascades between the 0 2 + -2 1 + -0 1 + level sequences. The results of g=0.42±0.07 for102Mo and ofg= ?0.11 +0.12 for104Mo agree with the prediction of the vibrational-rotational model. In terms of IBA, with the assumption ofN π=3 for the Mo isotopes which takes into consideration a two particle, two-hole excitation across the Z=40 subshell, the proton-bosong factor is deduced to beg π=1.00±0.23. It is shown that this value provides evidence for subshell effects in100Zr. |
