“…Therefore, continuing the study of thermonuclear reactions on the basis of the MPCM [10,32] with separation of orbital states according to Young tableaux, let us consider the astrophysical S-factor of the radiative proton capture on 3 H at energies of 1 keV-5 MeV and the rate of this reaction from T 9 = 0.01 to T 9 = 5. Preliminary results for the S-factor of this reaction at astrophysical energies in the frame of the MPCM were given in [38,39]. In the current work new results for the rate of the proton capture on 3 H have been obtained and compared those in [38,39].…”

In the current work new results for the rate of the proton capture on 3 H have been obtained and compared those in [38,39]. The potentials of the scattering processes and bound p 3 H states are improved and detailed classification carried out for the orbital states of the p 3 H system according to Young tableaux and isospin.…”

“…In our earlier works [10,[32][33][34][35][36][37] the possibility of describing astrophysical S-factors or total cross-sections of radioactive capture for three dozen processes on the basis of two-body potential cluster model (PCM) was demonstrated. Preliminary results [38,39] were obtained for p 3 H-capture at astrophysical energies. The calculations of these reactions were carried out on the basis of the modified variant of PCM (MPCM) with forbidden states (FSs) and classification of states according to Young tableaux [40].…”

Calculations of the reaction rate of the proton radiative capture on 3 H at temperatures from 0.01 Т 9 up to 5 Т 9 , which are based on the theoretical results for the astrophysical S-factor and take into account the latest experimental data, were carried out. Theoretical results for the S-factor at energies from 1 keV up to 5 MeV were obtained in the framework of the modified potential cluster model with the classification of orbital states according to Young tableaux. On the basis of used nuclear model of the interaction of p and 3 H particles there was shown possibility of description the latest experimental data for the S-factor at the energy range from 50 keV up to 5 MeV. Numbers: 21.60.Gx, 25.40.Lx, 26.35.+c, 26. Reaction No.12 proceeds with comparatively low probability, since the E1 process is forbidden by the isospin selection rules. This leads to the factor   J J J

“…From the theoretical side, different two-body and three-body potential models [14][15][16][17][18][19][20][21] and ab initio approaches [22] have been developed. These studies have demonstrated that the main contribution to the process at energies around and beyond the 3 + resonance comes from the E2 transition.…”

Theoretical study of theα+d→Li6+γastrophysical capture process in a three-body model

The astrophysical capture process α + d → 6 Li + γ is studied in a three-body model. The initial state is factorized into the deuteron bound state and the α + d scattering state. The final nucleus 6 Li(1+) is described as a three-body bound state α + n + p in the hyperspherical Lagrange-mesh method. The contribution of the E1 transition operator from the initial isosinglet states to the isotriplet components of the final state is estimated to be negligible. An estimation of the forbidden E1 transition to the isosinglet components of the final state is comparable with the corresponding results of the two-body model. However, the contribution of the E2 transition operator is found to be much smaller than the corresponding estimations of the two-body model. The three-body model perfectly matches the new experimental data of the LUNA collaboration with the spectroscopic factor 2.586 estimated from the bound-state wave functions of 6 Li and deuteron.

The modified potential cluster model with the forbidden states and the classification of states according to the Young tableaux, which are irreducible representations of permutation symmetric group SU(4), was used in this paper. Within the framework of this model the possibility of describing the experimental data available for the total reaction cross sections and the reaction rate of neutron radiative capture on 10 Be at thermal and astrophysical energies has been shown.
