The intense γ-rays from classical novae are emitted due to the β-decay of 18F which is produced by the Hot-CNO cycle. The reaction rate of 18F(p,α)15O affects the prediction of the abundance of 18F. The main contribution to this reaction rate is from the resonances in 19Ne near and above the proton threshold. Hence, many experiments and theoretical works have been performed on the low-lying 18F+p resonances. One of the methods for investigating 19Ne parameters is studying the mirror nucleus 19F. α elastic scattering experiment was performed with a 7 MeV/u 15N beam for investigating the resonance parameters in 19F using the thick target method in inverse kinematics at the radioactive beam facility CRIB of the Center for Nuclear Study, the University of Tokyo. The excitation function of 19F was obtained for the excitation energy Ex = 6.7 - 7.7 MeV, and the parameters of the resonance states in 19F were determined using an R-matrix analysis.
