Abstract：
Through measuring high-fold prompt γ-ray coincidence events following the spontaneous fission of ²⁵²Cf with the Gammasphere detector array, new level scheme in the very neutron-rich ¹¹²Ru nucleus has been established.The ground-state band and the one-phonon γ-vibrational band have been confirmed and extended with spin up to 16h and 15h, respectively. The other two side bands, one proposed as two-phonon γ-vibrational band and another proposed as two-quasiparticle band, have been identified for the first time. From cranked shell model calculations, ¹¹²Ru nucleus may have triaxial deformation with parameters β₂～0.27, γ～－29° and the band crossing in the yrast band is due to the alignment of two h_11/2 neutrons. The characteristics for the quasiparticle band and γ-vibrational bands have also been discussed.
