Abstract

²²Mg, ³⁰S, ³⁴Ar and ³⁸Ca have been investigated using (p,t) reactions at RCNP with the intent of identifying energy levels in nuclei that determine the reaction rates along the pathway of the αp-process. These experiments exploit the high resolution and 0° capabilities of the Grand Raiden spectrometer and the WS beamline, which can deliver a fully dispersion matched beam to target. The level information is vital to understanding the nucleosynthesis occurring during explosive hydrogen burning, which, for example, is thought to occur during type I X-ray bursts. In the case of ²²Mg, new reaction rate calculations have been performed for the ¹⁸Ne(α,p)²¹Na reaction. The experimental technique will be discussed, and the experimental results will be presented.
