“…For the thickness calculation a pure carbon layer was assumed and the proton stopping power in carbon was taken from the SRIM code [25]. The stopping power provided by SRIM is in perfect agreement with the precise experimental data of S. Gorodetzky et al [26] which have at most 2.3 % uncertainty in the energy range of the resonance. Therefore, this 2.3 % was taken as the stopping power uncertainty.…”

The CNO cycle is one of the fundamental processes of hydrogen burning in stars. The first reaction of the cycle is the radiative proton capture on $$^{12}$$ 12 C and the rate of this $$^{12}$$ 12 C(p,$$\gamma $$ γ )$$^{13}$$ 13 N reaction is related to the $$^{12}$$ 12 C/$$^{13}$$ 13 C ratio observed e.g. in the Solar System. The low-energy cross section of this reaction was measured several times in the past, however, the experimental data are scarce in a wide energy range especially around the resonance at 1.7 MeV. In the present work the $$^{12}$$ 12 C(p,$$\gamma $$ γ )$$^{13}$$ 13 N cross section was measured between 300 and 1900 keV using the activation method. This method was only used several decades ago in the low-energy region. As the activation method provides the total cross section and has uncertainties different from those of the in-beam $$\gamma $$ γ -spectroscopy technique, the present results provide a largely independent data set for future low-energy extrapolations and thus for astrophysical reaction rate calculations.

“…As the best choice of the energy-loss rate for a backscattered channeled ion is close to that in the random direction [8], the directional dependence of the energy-loss rate is, for simplicity, not taken into account. Values of the stopping power have been calculated from [9].…”
