Abstract
The Doppler shift attenuation method has been used to make two measurements of the mean life of the 320-keV level. The results are 150±30 fs from the reaction and 168±17 fs from the reaction. The adopted value of 166±15 fs, from the present and previous measurements, corresponds to an extremely strong transition of 0.36±0.03 W.u. The adopted energy of the ground state transition from this and previous measurements is 320.04±0.10 keV. It is shown that the magnitude of this transition can be understood on the basis of shell-model calculations only if realistic single-particle wave functions are used. A similar theoretical treatment is given for strong transitions in and .
