Abstract

The level structure of 30S was studied via the 28Si(3He,n) and 32S(p,t) reactions at the Nuclear Science Laboratory of the University of Notre Dame and the Research Center for Nuclear Physics of the University of Osaka, Japan. Important experimental information on the energy levels, decay branching ratios, and tentative spin assignments is extracted to calculate the reaction rates for 29P(p,γ)30S and 26Si(α,p)29P, which play a critical role in the reaction flow in explosive hydrogen burning.
