Exploring the {sup 22}Ne(p,γ){sup 23}Na reaction at LUNA and at HZDR
- Dipartimento di fisica, Università di Genova, and INFN Sezione di Genova, Genova (Italy)
The {sup 22}Ne(p,γ){sup 23}Na reaction is involved in the hydrogen burning NeNa cycle. This determines the nucleosynthesis of the Ne and Na isotopes in the Red Giant Branch and Asymptotic Giant Branch phases of stellar evolution. In the energy range relevant for astrophysics (20 keV < E < 600 keV), the {sup 22}Ne(p,γ){sup 23}Na reaction rate is highly uncertain because of the contribution of a large number of resonances never measured directly. A related study is under preparation at the Laboratory for Underground Nuclear Astrophysics (LUNA), in the Gran Sasso National Laboratory, and it will cover the energy range 100 keV < E < 400 keV. Meanwhile, a measurement at higher energies (i.e. 436 keV) has been carried out at the Tandetron accelerator of the HZDR (Helmholtz Zentrum Dresden Rossendorf) in Germany. Some preliminary results will be presented.
