Measurement of [sup 17]F+p reactions at RESOLUT

Abstract

The 14O(α,p)17F reaction is important for understanding the αp process that occurs in X-ray bursts, but the rate of this reaction remains uncertain due to the uncertain properties of states in 18Ne. We measured the 17F(p,p)17F and 17F(p,α)14O reactions to study the properties of states in 18Ne that are important for the 14O(α,p)17F reaction using 17F radioactive beams from the RESOLUT facility at Florida State University. Double-sided silicon strip detectors were used to detect light particles, and recoiling heavy ions were detected in coincidence using a gas ionization chamber at forward angles. The performance of the system was first tested using the 17O(p,α)14N reaction. This was the first measurement using the ASIC electronics and recoil detector being developed for the Array for Nuclear Astrophysics Studies with Exotic Nuclei (ANASEN). We report on the performance and preliminary results.
