• A method of calculation is described to estimate the average number of neutronsemitted per fragment in medium-excitation fission from published experimental data onneutron emission in thermal-neutron induced fission, average total kinetic energy as afunction of fragment mass and mass yield in low- and medium-excitation fission reactions.Use is made of a relation of fragment excitation energy with internal excitation anddeformation energies, and the difference in kinetic energy between the fission reactionsat two-excitation energies. A tentative calculation is made for the fission of <SUP>238</SUP>U inducedby 12 MeV protons. The results are in good agreement with experimental data.<BR>The method developed in the present work may make it possible to predict theaverage number of neutrons emitted from individual fragment in medium-excitation fis-sion which has not yet been measured experimentally.
