The extraction of fractions of the resonant component from analyzing powers in ~6Li(d, a)4He and ~6Li(d, po)7Li reactions at very low incident energies

摘要

Recently, several groups deduced the astrophysical S(E) factor for 6Li+d reactions at zero energy using cross section data for astrophysical interests [1, 2]. Generally astrophysical S(E) factor at zero energy was extrapolated from data which is not affected by electron screening. The extrapolated S(E) factor depends on the reaction model. The model dependence especially appears when the cross section has two components, resonant component and nonresonant one. In this work, we extracted the fraction of the resonant component in the ~6Li(d,a)4He and ~6Li(d,p)7Li reactions using polarization observables.
