Within the framework of the modified potential cluster model with forbidden states, we have considered the astrophysical S-factor of radiative р13N capture at low energies. The S-factor is calculated on the basis of the E1 transition to the bound 3Р0 state of the 14O nucleus in the р13N channel from the 3S1 wave of р13N scattering in the energy range from 30 keV to 7 MeV, which includes a resonance at 0.545 (1–) MeV (c.m.). The S-factor in the energy range 30–70 keV proved to be practically stable and equal to 7.3(2) keV·b. Next, we obtained the reaction rate in the temperature range from 0.01 T9 to 10 T9, which is in general agreement with the results of works by Li (2006), Tang (2004), and Magnus (1994). However, the obtained reaction rate at some temperatures is up to two times greater than the results of Decrock (1993). The reaction rate is approximated by a simple analytical expression.
