摘要：

The Ne-22(p,gamma)Na-23 reaction is a part of the hydrogen burning NeNa cycle. In second-generation stars hydrogen burning may proceed via this cycle. The rate of the Ne-22(p,gamma)Na-23 reaction depends on the strength of several resonances in the energy range of the LUNA 400 kV accelerator which have never been observed in direct experiments. A related study is under preparation at LUNA.
