Astrophysical factor for the radiative capture reaction alpha+d>Li6+gamma
Mukhamedzhanov, AM; Schmitt, R. P.; Tribble, Robert E.; Sattarov, A. (American Physical Society, 1995)We consider the radiative capture process alpha+d>Li6+gamma at energies, E(c.m.)less than or equal to 300 keV, that are relevant for astrophysical processes. Due to the peripheral character of the reaction, the overall ...

Sattarov, A.; Mukhamedzhanov, AM; Azhari, A.; Gagliardi, Carl A.; Trache, L.; Tribble, Robert E. (American Physical Society, 1999)The Be9(p, gamma) B10 reaction plays an important role in primordial and stellar nucleosynthesis of light elements in the p shell, but the energy dependence of S(E) has not been well understood.
