The inelastic component of the key astrophysical resonance (

) in the 14O(α,p)17F reaction has been studied by using the resonant scattering of 17F+p. The experiment was done at REX-ISOLDE CERN with the Miniball setup. The thick target method in inverse kinematics was utilized in the present experiment where a 44.2 MeV 17F beam bombarded
