In recent years collectivity in the mass region around A = 100 has become the focus of increased interest. The N = 52 isotones were investigated in detail and phonon excitations -especially one- and two-phonon mixed-symmetry states--were identified. In order to investigate how vibrator-like behavior and states with mixed-symmetry character evolve with increasing neutron number it is interesting to study the N = 54 isotones. Therefore an experiment to measure the low-spin excitations of {sup 100}Pd was performed at the FN-Tandem accelerator with the HORUS cube spectrometer. Besides the determination of excitation and transition energies and branching ratios, spins and multipole mixing ratios resulted from the {gamma}{gamma} angular correlation analysis. The newly gained data were compared with predictions from theory both from collective models and from shell model.
