Measurement of the cross section for the reaction [sup.20]Ne[sup.17]O in the neutron-energy between 4 and 7 MeV

The cross section for the reaction [sup.20]Ne(n, α)[sup.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.sub.0], [α.sub.1], [α.sub.2], and [α.sub.3] channels of the reaction [sup.20]Ne(n, α)[sup.17]O were obtained for the first time.
