An accurate knowledge of the level structure of ^30,31S above the proton threshold is important for calculating the astrophysical rates of proton capture on ^29,30P respectively. These proton captures affect the Si abundances observed in meteoritic presolar grains and the reaction flow to heavier nulcei in novae. We have studied ^30,31S by bombarding ZnS targets with ˜40-MeV proton beams from the Holifield Radioactive Ion Beam Facility and detecting reaction tritons and deuterons in the Silicon Detector Array (SIDAR). A total of 13(26) states were observed in ^30S(^31S) including 9(17) above the proton threshold. The spins of strongly-populated levels were constrained through a DWBA analysis of the measured angular distributions. The method and results will be presented.
