High-spin states in neutron-rich even-even Pd isotopes

Transitions among high-spin states in 112,114,116Pd are observed through prompt -ray spectroscopy following the spontaneous fisson of 252Cf. Spins and parities are assigned to many newly observed levels based on angular correlation analysis and comparison with known spins and parities of less neutron-rich Pd nuclides. The -band structures are significantly extended. New rotational band structures are observed for the first time, and tentatively assigned negative parity. IBA-1 model calculations are performed for the ground state and -bands.
