From γ-γ-γ and γ-γ-γ-γ coincidence studies of spontaneous fission of 252Cf, new high spin states in 148Ce were identified. The octupole bands with s = +1 and s = -1 are expanded with spins with 28+ and 18-, respectively. Importantly, a 1γ vibrational band has been established up to 14+ and a 1β vibrational band up to 6+. The levels in γ and β bands in 148Ce are compared systematically to those in neighboring 150Nd and 152Sm isotones. Further, this comparison informs the role of deformation and shape transition in this mass region. New 3- and 5- members of the s = +1 octupole band were observed.
