Abstract
Levels in the neutron-rich 105Mo nucleus have been investigated by observing prompt γ-rays following the spontaneous fission fragments of 252Cf with the Gammasphere detector array. The yrast band has been confirmed and updated. The other two collective bands with the band head levels at 870.5 and 1534.6 keV are newly observed, and they are suggested as the candidates for one-phonon K=9/2 and two-phonon K=13/2 double γ-vibrational bands, respectively. Systematic characteristics of these bands have been discussed.
