3He(α,γ)7Be and 3H(α,γ)7Li reaction rates and implication for Big Bang nucleosynthesis in the potential model

The reaction rates of the direct astrophysical capture processes 3He(α,γ)7Be and 3H(α,γ)7Li, as well as the abundance of the 7Li element are estimated in the framework of a two-body potential model...
