The O-17(p,alpha)N-14 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 O-17(p,alpha)N-14 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 O-17(p,alpha)N-14 reaction, measured by means of the THM, has been used to renormalize the corresponding resonance strength in the O-17 + p radiative capture channel.

Abstract
The O-17(p,alpha)N-14 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 O-17(p,alpha)N-14 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 O-17(p,alpha)N-14 reaction, measured by means of the THM, has been used to renormalize the corresponding resonance strength in the O-17 + p radiative capture channel.| File | Dimensione | Formato | |
