Cross sections for A = 6 and 7 isotopes in the 4He + 4He reaction

Description

The ratio of the total cross section for A = 7 products to that for A = 6 products is plotted for bombarding energies from 61.5 to 158.2 MeV. It is apparent that the α + α reaction cannot have any significant role in synthesizing sufficient 7Li to yield the solar-system abundance ratio 7Li/6Li = 12.5 for any mechanism invoking reactions induced by energetic particles (E > 50 MeV). Cosmological consequences of these results are discussed. 2 figures
