Production of A = 6 and 7 isotopes in the α + α reaction
Description
The yields of 6He, 6Li, 7Li, and 7Be the α + α reaction were measured from 61.5 to 158.2 MeV to provide data for evaluating models of light-element nucleosynthesis. The cross-sections for 7Li and 7Be formation were found to be identical, within errors. The ratio of total cross section for A = 7 production to that for A = 6 indicates that, for any mechanism that invokes reactions induced by particles with E > 50 MeV, the α + α reaction cannot have any significant role in synthesizing sufficient 7Li to yield the solar-system 7Li/6Li abundance ratio. 2 figures
