Post-accelerated radioactive ion beams produced at Louvain-la-Neuve, Belgium have been used to investigate the hot-CNO cycle breakout reaction O-15(alpha,gamma)Ne-19. This reaction not only leads to the synthesis of proton-rich nuclei via the rp-process but is also thought to initiate the massive release of energy which can trigger stellar explosions such as novae, supernovae and x-ray bursters. The properties of this reaction have been investigated via a study of the relevant decays of excited states in Ne-19. These resonances have been populated using an inverse Ne-18(d,p) reaction on a deuterated polyethylene target. Experiments have been carried out using an especially designed high granularity large solid angle silicon strip detector array consisting of 320 elements. The method, the experimental set-up, as well as results on the population and decay of states of astrophysical interest will be presented.
