Abstract

An introduction to nucleosynthesis, the creation of the elements in the big bang, in interstellar matter and in stars is given. The two-step process 4He(2n,γ)6He and the reverse photodisintegration 6He(γ,2n)4He involving the halo nucleus 6He could be of importance in the α-process in type-II supernovae. The reaction rates for the above processes are calculated using three-body methods and show an enhancement of more than three orders of magnitude compared to the previous adopted value. Direct-capture calculations give similar values for the above reaction rates. Therefore, this method was also used to calculate the reaction rates of the two-step processes 6He(2n,γ)8He and 9Li(2n,γ)11Li and the reverse photodisintegration of 8He and 11Li that could be also of importance in the α-process.
