The reaction Ne(α,p)Na, of importance to nuclear astrophysics, has been studied directly using the postaccelerated radioactive Ne beam available at Louvain-la-Neuve and a gaseous helium target. This study covered the energy region from 2.04 to 3.01 MeV in the center of mass, and identified various levels in the compound nucleus Mg. The stellar reaction rate due to these states has been deduced. The experimental rate shows good agreement with theoretical predictions [J. Görres, M. Wiescher, and F. K. Thielemann, Phys. Rev. C 51, 392 (1995)] above 2.5 GK.
