Description
Resonant elastic scattering of a radioactive 20Na beam incident upon protons in a polyethylene target has been used to probe the level structure of 21Mg above the proton decay threshold. Three states have been observed, and their properties deduced through analysis based on the R-matrix formalism. The results improve and extend previous studies of this nucleus. An estimate of the 20Na(p,γ)21Mg reaction rate, including these new data, suggests this reaction will not play a significant role in explosive hydrogen burning in astrophysical sites such as novae and x-ray bursts
