Reaction rate for radiative p13N capture
Within the framework of the modified potential cluster model with forbidden states, the astrophysical S -factor of radiation p 13N capture in the low energy is considered. The S -factor was calculated based fo the E 1-transition to the bound 3 P 0 state of the 14O nucleus in the p 13N-channel from the 3 S 1 p 13N scattering wave in the energy range from 30 keV to 7 MeV, which includes a resonance at 0.545 (1-) MeV (ts.m.). The S -factor in the energy range of 30-70 keV turned out to be almost stable and equal to 7.3 (2) keV×b. Further, the reaction rate was obtained in the temperature range from 0.01 to 10 T 9, which is generally consistent with the results of Li 2006, Tang 2004, Magnus 1994. However, at some temperatures it is up to 2 times higher than the results of Decrock 1993. The reaction rate was approximated by a simple analytical expression.
