Abstract
The lifetimes of the first excited states of and have been measured using a pulsed Van de Graaff beam, with a slanted-target technique to reduce the duration of beam pulses on the target. The mean lives of these levels are (3.73±0.23) nsec for , and (1.04±0.02) nsec for . This result for , together with recent gamma angular distribution and stripping measurements, confirms the spin and parity of the first excited state of as .
