Reinvestigation of two-phonon γ-vibrational band in neutron-rich 114Pd
Abstract
The level structure in neutron-rich 114Pd nucleus has been reinvestigated by measuring prompt γ rays emitted in the spontaneous fission of 252Cf. A two-phonon γ-vibrational band built on the 1639.3keV level is observed, which confirms the previous suggestion from a β-decay experiment. Systematical comparison supports the assignment for a two-phonon γ-vibrational band in 114Pd. Triaxial projected shell model calculations for the multi-phonon γ bands of 114Pd are in good agreement with the experimental data.
