Lifetimes of the First Two Levels in 30P
Abstract
The lifetimes of the first two levels in 30P were measured by the attenuated-Doppler-shift technique. The measurements were analyzed by use of the universal stopping cross section given by Lindhard, Scharff, and Schiott, and a mean life τ=(1.55+/-0.30)×10-13 sec was obtained for the first level; for the second level only a lower limit (τ>=3.0×10-12 sec) was obtained. The experimental result for the first level is compared with the value calculated from the corresponding Gamow-Teller β transition according to the relation given by Kurath. Slightly revised energies of 677.0+/-1.0 and 709.0+/-1.0 keV are assigned to these levels.
