Within the framework of the modified potential cluster model with the classification of orbital states according to Young’s diagrams, the possibility of describing the experimental data for the total cross sections of radiative

C capture to the ground and first excited states of the

C nucleus at energies from 10 meV (1 meV = 10

eV) to 5 MeV is considered. It is shown that it is quite possible to explain values of the known experimental cross sections only based on E1 transitions from some

C scattering states, taking into account the first resonance at 153 keV. Based on theoretical total cross sections, the capture reaction rate has been calculated in the temperature range from 0.01 to 10.0 Т
