Investigation of the ^sup 19^F(n, [alpha])^sup 16^N reaction excitation function in neutron energy range of 4-7.35 MeV

New method based on ionization chamber with Frisch grid and digital signal processing was developed for experimental investigation of 19F(n, [alpha])16N reaction. The chamber filling gas with CF4 additive was used as the fluorine-containing target. The experimental investigation of 19F(n, [alpha])16N reaction cross-section in 4-7.35 MeV energy range is represented in this work. The total cross section of 19F(n, [alpha])16N reaction was measured as well as partial cross-section for sum of [alpha]0-[alpha]3 and sum of [alpha]4 and [alpha]5 reaction channels.
