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.
