Experimental angular distribution for the ¹⁹F(α, p)²²Ne reaction (﹩\tfrac{d\sigma }{d{\rm{\Omega }}}﹩ vs. ϑ_C.M, where ϑ_C.M is the emission angle of the proton in the center-of-mass reference frame of the reaction). The blue solid circles are the present experimental data. The red line represents a fit to the experimental data done by means of a linear combination of J^π = 3/2⁺ and J^π = 5/2⁺ angular distributions, using the equations given in Blatt & Biedenharn (1952) and La Cognata et al. (2015). The black, green, and blue lines are instead angular distributions for J^π equal to 3/2⁻(with ﹩{{\rm{a}}}_{3/{2}^{-}}﹩ as normalization coefficient), 1/2⁺, and 1/2⁻ (multiplied by a factor of two to separate it from the preceding distribution). See the text for details.
