THM determination of the 65 keV resonance strength intervening in the ~(17)O(p,a)~(14)N reaction rate

摘要

The ~(17)O(p,a)~(14)N reaction is of paramount importance for the nucleosynthesis in a number of stellar sites, including red giants (RG), asymptotic giant branch (AGB) stars, massive stars and classical novae.We report on the indirect study of the ~(17)O(p,a)~(14)N reaction via the Trojan Horse Method by applying the approach recently developed for extracting the resonance strength of the narrow resonance at E_(c.m.)~R=65 keV (E_X =5.673 MeV). The strength of the 65 keV resonance in the ~(17)O(p,α)~(14)N reaction, measured by means of the THM, has been used to renormalize the corresponding resonance strength in the ~(17)O + p radiative capture channel.
