Abstract

In explosive stellar hydrogen burning, the hot CNO cycles and the rp-process are mainly linked by the reaction sequence O(α, γ)Ne(p,γ)Na. Using intense Ne radioactive beams, both the Ne(p,γ) and the Ne(d,n) reaction have been studied. Upper and lower limits for the Ne(p,γ) reaction rate have been deduced, allowing to conclude that the O(α,γ) reaction is most likely the bottleneck reaction.
