Abstract

The current status of experimental data on inelastic p 4He scattering is reviewed, and the cross sections for respective channels are roughly estimated. These estimates make it possible to compute the amounts of 3He, 3H, and d nuclei produced in nonequilibrium cosmological nucleosynthesis to a precision of 10%. Investigation of inelastic p 4He scattering by using the method of accelerated 4He nuclei at E p75 MeV is of particular interest for cosmological applications because this allows one to achieve a higher precision in calculating nonequilibrium cosmological nucleosynthesis.
