Abstract

In Knowledge of the proton-proton (p-p) chain and CNO cycle are required for the evolution of main sequence stars during the early formation of the universe. In this study, we summarized the excitation functions of (p,γ) and (p,α) reactions for ⁷Be(p,γ)⁸B, ¹²C(p,γ)¹³N, ¹³C(p,γ)¹⁴N, ¹⁴N(p,γ)¹⁵O and ¹⁵N(p,α)¹⁵O in p-p chain and CNO cycle using EMPIRE and TALYS computer up to 10 MeV. The calculated data on nuclear fusion cross sections in hydrogen-burning stars were compared with theoretical TENDL-2014 and ENDF/B-VII data from EXFOR. The calculation results show closed agreement between the calculations and the data from literature.
