Abstract

The i13/2 ->h9/2 (M2) and s1/2 ->f7/2 (E3) reduced transition probabilities in 209Bi have been determined from the direct half-life measurement of the 13/2+ and 1/2+ states using the Romanian array for gamma-ray spectroscopy in heavy ion reactions (ROSPHERE). The 13/2+ and 1/2+ states were found to have T1/2=0.120(15) ns and T1/2=9.02(24) ns respectively. Angular distributions were used to determine an E3/M2 mixing ratio of delta=-.184(13) for the 1609 keV gamma-ray transitions de-exciting the 13/2+ state.
