n 13C capture reaction rate
Within the framework of the modified potential cluster model with the classification of orbital states according to Young's schemes, the possibility of describing the experimental data for the total cross sections of radiative n13C capture by the ground and first excited states of the 14C nucleus at energies from 10 meV (1 meV = 10-3 eV) to 5 МэВ is considered. It is shown that only basis on E 1 transitions from some states of n13C scattering, taking into account the first resonance at 153 kev, it is possible to fully explain the value of the known experimental cross sections. Further, basis on theoretical total cross sections, the reaction rate of the capture reaction in the temperature range from 0.01 to 10.0 Т 9 was calculated and its analytical parameterization was performed.
