Abstract
The prompt fission neutron spectra for the neutron induced fission of U-238 are calculated in the incident energy range where only the first fission c hance is involved using the multi-modal fission theory. The partial spectra of each fission mode are calculated on the basis of Los Alamos model and t he total spectrum is calculated by superposition of partial spectra weighte d with the respective probability of occurrence. The total fission spectra obtained in this manner are in good agreement with the experimental data. ( C) 2001 Elsevier Science Ltd. All rights reserved.
