Lifetime of the 3.56-MeV state of Li6

Leslie Cohen; Ralph A. Tobin

Abstract The bremsstrahlung beam from the U. S. Naval Research Laboratory 25-MeV betatron was used to excite the 3.56-MeV state in Li 6 . The gamma radiation resulting from the de-excitation of these nuclei was observed with and without a Li 6 absorber inserted in the primary beam. Assuming a spin assignment J = 0 for the excited state, and using a calculated Doppler with of 11.3 eV for enriched lithium metal, an analysis of the data yields a mean lifetime of (7.2 −1.3 +1.5 ) × 10 −17 sec.
