Abstract / Description of output
Resonant elastic scattering of a radioactive 20 Na beam incident upon
protons in a polyethylene target has been used to probe the level
structure of 21 Mg 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 20 Na(p,γ)21 Mg 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.
