Within the framework of the modified potential cluster model with a classification of orbital states according to Young's diagrams, the possibility of predicting the missing experimental data for the total cross sections of radiative n11B capture on the first excited state of the 12B nucleus at 0.95 MeV (2+) for the reaction energies from 10 meV (1 meV = 10-3 eV) to 7 MeV is considered. Based on the obtained total cross sections that take into account resonances up to 5 eV, the reaction rate is calculated at temperatures from 0.01 to 10.0 Т9. It is shown that low-lying resonances have a significant effect on the capture reaction rate. [ABSTRACT FROM AUTHOR]

The radiative p6Li capture process has been treated within the framework of the modified potential cluster model with forbidden states at energies from 10 keV to 10 MeV with allowance for the first excitation energy resonance at excitation energies exceeding the p6Li channel threshold by 7.2 or 1.6 MeV. The experimental data on the astrophysical S-factor are well reproduced based on the interaction potentials relevant to the bound state energies and the corresponding asymptotic coefficients. Based on the total cross sections calculated at energies from 1 keV to 5 MeV, the reaction rates of p6Li radiative capture have been calculated at temperatures in the range from 0.01 to 10 T9. The obtained reaction rates have been approximated by simple expressions easier to use in other works. [ABSTRACT FROM AUTHOR]

Within the framework of the modified potential cluster model with forbidden states, we consider radiative p2H capture at energies from 1 keV to 10 MeV. It is shown that on the basis of potentials that have been matched with the energy of the bound state and its asymptotic constant, it is possible to correctly reproduce the available experimental data. On the basis of the obtained total cross sections, a calculation of the reaction rate of p2H capture in the temperature range from 0.01 T9 to 10 T9 is performed. Results of this calculation are approximated by simple expressions, which simplifies their use in other studies. [ABSTRACT FROM AUTHOR]

In the frame of a modified potential cluster model based on the classification of orbital states according to Young diagrams and revised interaction potential parameters for the bound states of 7Be in the 3He4He cluster model with forbidden states, the astrophysical S-factor for the radiative capture reaction 3He(4He,γ)7Be has been calculated from 10 keV. The result obtained, S(23 keV) = 0.561 keV·b, reproduces the latest experimental data at 23 keV. The calculated and parametrized reaction rate is compared with some known results in the range of temperatures from 0.05 to 5 T9. [ABSTRACT FROM AUTHOR]

In the modified potential cluster model, the possibility of describing the astrophysical S-factor of radiative p7Ве→8Bγ capture to the ground state of the 8B nucleus at energies from 10 keV to 1 MeV is considered. Potentials of intercluster interactions, matched to the spectra of the 8B nucleus for scattering processes, and the potential of the bound 3Р2 ground state in the p7Ве cluster channel are constructed. The resonance in the 3P1 scattering wave at the energy 0.722 MeV, which leads to an М1-transition to the ground state, is considered. Total cross sections and the reaction rate of p7Ве capture are calculated in the temperature range from 0.01·Т9 to 5·Т9. [ABSTRACT FROM AUTHOR]

The possibility of describing the experimental data for the total cross sections of radiative nB capture to the ground state of the B nucleus at thermal and astrophysical energies is considered within the framework of the modified potential cluster model with classification of orbital states according to Young tableaux. It is shown that it is possible to explain the magnitude of the experimental cross sections at energies from 25.3 meV to 100 keV on the basis of just the E1 transition from the S state of nB scattering to the ground state of the B nucleus in the nB channel. New theoretical results have been obtained for the total cross sections of nB capture to the ground state of the B nucleus. The rates of both reactions are calculated in the temperature range from 0.01 to 5.0 Т. [ABSTRACT FROM AUTHOR]
