In explosive environments such as novae and X-ray bursts, hydrogen-rich material is mixed with heavier seed nuclei under extreme conditions. Proton-capture reactions occur quickly and release energy that drives the explosion. To understand these events, we must understand the rates of proton-capture reactions on radioactive nuclei. At the ORNL Holifield Radioactive Ion Beam Facility, some of the first direct measurements of proton-capture on exotic beams are being made. This talk will focus on the experimental techniques and the first results of these studies.
