The cross section for the reaction 20 Ne(n, α) 17 O was measured in the neutron-energy range 4-7 MeV. An ionization chamber equipped with a Frisch grid combined with a pulse-shape digitizer was used as a detector. Gaseous neon that served as a target on which the reaction being studied proceeded was added to the gas filling the ionization chamber. The partial cross sections for the α 0 , α 1 , α 2 , and α 3 channels of the reaction 20 Ne(n, α) 17 O were obtained for the first time.
