The reaction ²⁰Ne(p,γ)²¹Na is known to be crucial for the evolution of the Neon-Natrium-Cycle in stars. At the University of Notre Dame, Institute for Structure and Nuclear Astrophyics, we have studied the direct capture reaction in the astrophysically interesting region of E_p = 500 keV − 1400 keV with different setups of NaI and Ge detectors. The results of these experiments will be presented and discussed.
