Abstract

A method has been developed that can provide beams of many short-lived nuclei of interest in nucleosynthesis along the rp process path. With a ¹⁷F beam (T_1/2=64s) the excitation function of the ¹⁷F(p, α)¹⁴O reaction was measured to determine properties of excited states in ¹⁸Ne. These states influence the rate of the ¹⁴O(α, p)¹⁷F reaction which is important for understanding energy generation and nucleosynthesis in x-ray bursts. The present direct measurements yield a pattern of resonances and cross sections which differ substantially from previous estimates.
