Abstract
Measurements of Doppler shifts of rays from nuclei recoiling in gas are described. Mean lives of the 0.87-MeV state in , of the 0.58- and 0.97-MeV states in , and of the 0.41-, 0.93-, 1.32-, and 1.41-MeV states in produced by () reactions were obtained from these Doppler shifts. The effect on these mean lives of a variation in the deuteron current has been investigated. Finally, the known mean lives of the 0.87-MeV state in and the 0.58-MeV state in were used, together with the measured Doppler shifts, to obtain information concerning the slowing down of and ions in krypton gas.
