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