The 17F(p, γ)18Ne direct capture cross section
The 17F(p,γ)18Ne reaction is important for understanding nucleosynthesis in novae. This reaction rate is expected to be dominated by the unmeasured direct-capture cross section at nova temperatures. We have measured cross sections for the proton-transfer reaction 14N(17F,18Ne)13C to determine 17F+p asymptotic normalization coefficients for 18Ne bound states and the 17F(p, γ)18Ne direct-capture cross section. Elastic scattering cross sections for the 14N(17F,17F) 14N and 12C(17F,17F) 12C reactions were also measured and used to determine reliable optical-model parameters within the framework of a microscopic double-folding model. Here we present the technique and some preliminary results. © 2004 Elsevier B.V. All rights reserved.
