Abstract
Inexplosive stellar hydrogen burning, the hot CNO cycles and the rp-pr ocess are mainly linked by the reaction sequence O-15(alpha,gamma) Ne- 19(p,gamma)Na-20. Using intense Ne-19 radioactive beams, both the Ne-1 9(p,gamma) and the Ne-19(d,n) reaction have been studied. Upper and lo wer limits for the Ne-19(p,gamma) reaction rate have been deduced, all owing to conclude that the O-15(alpha,gamma) reaction is most likely t he bottleneck reaction.
