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 E_c.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.
