He4+H3 and He4

The 3 H(α, γ)7 Li and 3He(α, γ)7 Be Radiative Capture Reactions in a Wide Energy Range

“…References to experimental data denoted by the symbols in this figure are given in Ref. [2]. The obtained curve agrees reasonably well with the modern data up to vicinity of the 7/2resonance.…”

“…The intensities of the central Majorana force g c and the spin-orbit interaction g ls involved in this potential as adjustable parameters are equal to 0.977 and 3.469 respectively. These values were set to describe nuclear phase shifts of elastic scattering in the entrance channels of the reactions [2].…”

“…where E G is the Gamow energy of the colliding nuclei, E c.m. is their relative motion energy in the center-of-mass system, σ 0 and σ 1 are the total cross sections related to the captures to the ground and first excited states of the final nucleus respectively, and σ is the total cross section of the reaction [2].…”

“…Experimental data are also marked in these figures (see Ref. [2] for references). The calculated curves are in a very good agreement with the data [4] in the whole energy range.…”

“…The latter reaction is also important to study stellar nucleosynthesis, especially in the Sun. Despite a long story of experimental and theoretical investigations of these reactions (see references cited in works [1,2]), the required precision has not been achieved yet. As a result, the problems still remain.…”
