Abstract
The stellar reaction 14O(α,p)17F, that critically determines the onset of the hightemperature rp-process, has been studied through a direct measurement with a low-energy radioactive 14O beam and a gaseous helium target cooled down to 30 K. The reaction cross section was measured directly by means of a thick target technique in the energy range of Ec.m(l4O+α) = 0.8-3.8 MeV. The 14O(α,p)17F* reaction leading to the first excited state in 17F was clearly observed for the first time, suggesting an increase of about 50% for the stellar reaction rate through resonances at around 7.1 MeV in 18Ne. © 2004 Published by Elsevier B.V.
