Abstract
Excitation functions have been measured at five angles for the 19F(α, α) 19F scattering process up to E α = 3.7 MeV. The yield curves for the 19F(α, γ) 23Na , 19F(α, p 0) 22Ne and 19F(α, p 1γ) 22Ne reactions were also obtained in simultaneous measurements. A multi-level R-matrix calculation was used to analyse the elastic scattering data, yielding parameters for 16 resonances. Sixty resonances corresponding to levels in 23Na were seen in the different reactions. A comparison of resonance energy and total width data is given. The 19F(α, γ) 23Na reaction below E α = 2.3 MeV was studied also with thick-target measurements. Decay schemes are given for two resonances. The α-particle strength is discussed.
