Range distributions for fluorine ions in ¹⁹F⁺-implanted KTiOAsO₄ (KTA) in an energy range of 80–350 keV were measured by using the ¹⁹F(p, αγ)¹⁶O resonant nuclear reaction at E_R = 872.1 keV, with width Γ = 4.2 keV. A proper convolution calculation method was used to extract the true distributions of fluorine from the experimental excitation yield curves. The experimental range distribution parameters, R_p and ΔR_p, were compared with those obtained from Monte Carlo simulation codes.
