Alpha particles produced by the interaction of 14-Mev neutrons with sodium are studied with the help of Ilford 200- mu m nuclear emulsion plates. The energy distributions of the alpha particles agree with predictlons of evaporation theory. The angnlar distributions are consistent with compound nucleus formation in the sense that they show a symmetry about 90 deg . The relative level density calculated from the energy distribution of the alpha particles fits exactly a straight line corresponding to a Maxwellian distribution with a temperature of 1.55 Mev, The total (n, alpha ) cross section is estimated to be 185 mb plus or minus 15%.
