Abstract

The lifetime of the 1.042-MeV T=1 state in F18 was measured by use of the attenuated-Doppler-shift method. Analysis of the measurements by use of the universal stopping cross section given by Lindhard, Scharff, and Schiott give a mean life τ=(0.40.2+0.3)×1014 sec. The experimental lifetime agrees with the value calculated from the corresponding Gamow-Teller β transition according to a relation given by Kurath. The accuracy of the universal stopping cross section is discussed.
