Gamow-Teller strength of Mg-26
MetadataShow full item record
We have measured cross sections for (d,He-2)-induced reactions on Mg-26 at an energy of E(d)=125.2 MeV. The measured Gamow-Teller strength is significantly smaller than that inferred from (p,n) reactions. We demonstrate that beta(+) Gamow-Teller strengths for T-0 + 1 states deduced from (p,n) reactions may have significant systematic uncertainties due to ambiguities in the large backgrounds that must be subtracted.
