(γ,α)/(γ,n) branching points relevant to the γ-process nucleosynthesis
Published: January 2020 Simon
In order to improve the description of the reaction flow in the astrophysical γ-process, the (α,γ) cross sections were measured for 90Zr, 102Pd, 108Cd, and 110Cd using a γ-ray summing detector, HECTOR, to pinpoint the nuclei at which the (γ,α) become dominant over the (γ,n) reactions and redirect the nucleosynthesis path towards lighter nuclei. As a result a new branching point at 114Sn was identified for T9<1.7 GK. Learn more
