The α+d→L6i+γ$\alpha + d \to {}^{6}{\rm{Li}} + \gamma $ reaction and the second Lithium puzzle

Abstract

A brief review on the second Lithium problem is presented. In particular the focus is on the α+d→L6i+γ$\alpha + d \to {}^{6}{\rm{Li}} + \gamma $ reaction and on the details of the different α−d$\alpha - d$ potential models and the theoretical approximations done during the evaluation of the astrophysical S-factor.
