Two of the main components of nuclear fusion processes which occur in stars are the radiative capture of deuteron-alpha and its inverse reaction during which helium transforms …
The D (p, γ) He 3 reaction, where 'D'denotes 'H 2', is of primary importance in cosmology and nuclear physics since it offers a unique opportunity to test predictions based on the …
The astrophysical S factor and reaction rates of the direct capture process Li 6 (p, γ) Be 7 are estimated within a two-body single-channel potential model approach. Nuclear potentials of …
