The 22Ne(p,γ)23Na reaction is involved in the hydrogen burning neon-sodium cycle. In second-generation stars, where the central temperature is higher than 0.05 109 K, hydrogen burning can proceed also via the NeNa cycle. The 22Ne(p,γ)23Na cross section, dominated by a large number of resonances never measured directly, is still affected by large uncertainties.
At the Laboratory for Underground Nuclear Astrophysics (LUNA), in the Gran Sasso National Laboratory in Italy, several cross sections have been measured in the past down to the energies of astrophysical interest. An experimental study of the 22Ne(p,γ)23Na reaction is under preparation at LUNA, using a windowless gas target system and two HPGe detectors.
