Abstract
The mean lives of the three lower levels in have been measured with a new version of the Doppler-shift-attenuation method, using a gas as target and absorber. The reaction was at energies ranging from 5.5 to 8 MeV. The results for the mean lives are the following: psec for the 372-, 593-, and 990-keV levels, respectively. In addition, the relative intensity of rays from the decay of the levels have been obtained at MeV. Electron-conversion measurements have also been carried out for the transitions 372→0 and 593→372 keV, which turn out to be almost pure .
