ELEMENTARY PARTICLE PHYSICS AND FIELD THEORY REACTION RATE OF [p.sup.6]Li CAPTURE

The radiative [p.sup.6]Li 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 [p.sup.6]Li 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 [p.sup.6]Li radiative capture have been calculated at temperatures in the range from 0.01 to 10 [T.sub.9]. The obtained reaction rates have been approximated by simple expressions easier to use in other works.
