NEW ASTROPHYSICAL REACTION RATE FOR THE C-12(alpha, gamma)O-16 REACTION

摘要

A new astrophysical reaction rate for C-12(alpha, gamma)O-16 has been evaluated on the basis of a global R-matrix fitting to the available experimental data. The reaction rates of C-12(alpha, gamma)O-16 for stellar temperatures between 0.04 <= T-9 <= 10 are provided in a tabular form and by an analytical fitting expression. At T-9 = 0.2, the reaction rate is (7.83 /- 0.35) x 10(15) cm(3) mol(-1) s(-1), where stellar helium burning occurs.
