Abstract:
The 22Ne(α, γ)26Mg reaction is the main competitor of the 22Ne(α, n)25Mg reaction which is the main source of neutrons for the s-process in low-mass asymptotic giant branch (AGB) and massive stars. The 22Ne(α, γ)26Mg reaction rate uncertainty is mainly due to the 395 keV resonance which has been studied only indirectly leading to a wide range of possible values for its resonance strength (10 -14-10 -9 eV). In this paper I will describe the direct measurement of the 395 keV resonance of the 22Ne(α, γ)26Mg reaction at the LUNA facility (Laboratory for Underground Nuclear Astrophysics), located at Gran Sasso National Laboratory. A description of the setup, measurement strategy, and some very preliminary results are presented.
