N2 - 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.
