Direct capture cross sections at low energy

Creators

Abstract

We derive simple expressions for the low-energy behavior of direct radiative capture cross sections, particularly those important in solar nucleosynthesis, such as (^3)He(α,γ)(^7)Be, (^3)H(α,γ)(^7)Li, and (^7)Be(p,y)(^8)B. Our results for the (^3)He(α,γ)(^7)Be reaction are inconsistent with a measurement by Rolfs et al. [NUCLEAR REACTIONS (^3)He(α,γ)(^7)Be, (^3)H(α,γ)(^7)Li, E<300 keV, (^7)Be(p,y)(^8)B, l E
