Direct Measurement of the 26Al(a,p) Reaction Cross-Section

ORAL

Abstract

The 26Al(a,p) reaction impacts final abundances in lower-temperature X-ray burst models. We have performed a direct thin-target measurement of this reaction at several energies approaching the Gamow window, by impinging a batch-mode beam of 10^6 26Al ions/s from the ReA3 accelerator on the JENSA gas-jet target. Ejectiles were detected using the ORRUBA silicon detector array and recoils were detected using the GODDESS position-sensitive fast ionization chamber. This approach enables determination of partial and total reaction cross sections, providing stringent constraints on Hauser-Feshbach predictions. An overview of the experiment and some preliminary results will be presented. Work supported in part by the US Department of Energy (Office of Science and National Nuclear Security Administration) and the National Science Foundation.
