A Study Of ^22Ne(p,γ)^23Na Using (^3He,d) Spectroscopy
Abstract
The sodium-oxygen anticorrelation observed in globular-cluster giants is thought to arise when the byproducts of the NeNa cycle are mixed to the stellar surface.(Langer, et al., 1993, Pub. Astron. Soc. Pac., 105, 301) In this picture, sodium is produced by ^22Ne(p,γ)^23Na. At the low temperatures of interest, this reaction proceeds primarily via low-lying resonances whose strengths are expected to be immeasurably small. However, it is possible to obtain the information of interest, proton partial widths Γ_p, through proton stripping measurements. We have measured angular distributions for the ^22Ne(^3He,d)^23Na reaction using the TUNL Enge splitpole spectrometer with a newly-constructed focal-plane detector. Initial results will be presented along with their implications for the mixing scenario.
