A NOVEL APPROACH TO MEASURE THE CROSS SECTION OF THE O-18(p, alpha)N-15 RESONANT REACTION IN THE 0-200 keV ENERGY RANGE
Original language description
The O-18(p, alpha)N-15 reaction is of primary importance to pin down the uncertainties, due to nuclear physics input, affecting present-day models of asymptotic giant branch stars. Its reaction rate can modify both fluorine nucleosynthesis inside such stars and oxygen and nitrogen isotopic ratios, which allow one to constrain the proposed astrophysical scenarios. Thus, an indirect measurement of the low-energy region of the O-18(p, alpha)N-15 reaction has been performed to access, for the first time, the range of relevance for astrophysical application. In particular, a full, high-accuracy spectroscopic study of the 20 and 90 keV resonances has been performed and the strengths deduced to evaluate the reaction rate and the consequences for astrophysics.
