Abstract
The scattering of monoenergetic neutrons by neon in the neutron energy range 1.9 to 3.5 MeV has been investigated by measuring the neon recoils in a multiple-wire proportional counter with which a γ-ray background can be reduced to a very low value by an anticoincidence technique. Approximate values for the total cross-section are obtained, which show resnance peaks at 1.94, 2.00, 2.11, (2.45), 2.57, 2.73, 2.88, and 3.37 MeV neutron energy. By the study of angular distributions the resonances at 1.94 and 2.00 MeV could be ascribed to a 3 2 + and a 3 2 − level in the 21Ne nucleus respectively. The strong resonance at 2.11 MeV seems to be due to both a 3 2 + and a 3 2 − level.
