摘要：

High-spin states in Pb-194 have been populated in the Er-168(Si-30, 4n) reaction at 142 MeV. The emitted. rays were detected by the EUROBALL III multidetector array. The level scheme was considerably extended and many previously observed. gamma-ray transitions were reordered. Four new magnetic rotational bands were observed. The energies and spins of the bandheads of all previously observed magnetic rotational bands were corrected based on the observation of new transitions. From nine observed bands, only one could not be connected to the lower lying states. Based on comparison systematics with neighboring Pb isotopes and tilted-axis cranking model calculations previously reported, configuration assignments to the observed bands have been made.
