Study of low-spin excitations in 100Pd

In the context of the investigation of collectivity in the A = 100 mass region an experiment to measure the low-spin excitations of Pd-100 was performed at the Cologne Tandem accelerator with the HORUS cube spectrometer. Besides the determination of excitation and transition energies and branching ratios, data on spins and multipole mixing ratios resulted from the gamma gamma angular correlation analysis. The level scheme was extended and clarified. Nearly 70 gamma transitions were identified. thereof 16 for the first time. In addition 11 new energy levels were assigned and 13 multipole mixing ratios were measured for the first time. The newly gained data are compared with theoretical predictions from collective models and the shell model. (C) 2009 Elsevier B.V. All rights reserved.
