AbstractAbstract
[en] Group constants for 235U and sup(239,240,241)Pu have been calculated in the 26-group approximation. The group constants differ from those obtained elsewhere mainly in original data on cross sections, energy and angular distributions of secondary neutrons and average resonance parameters. The group constants have been averaged over the 1/E (for E<2.5 MeV) and fission (E>2.5 MeV) spectra. The sigmasub(f),sigmasub(γ) and anti νsub(t) values are presented only for the energy range peculiar to fast reactors (0.1 keV< Esub(n)<10.5 MeV). Thus obtained group constants are shortly compared with the data, derived from the English (1970), German (1968) and BNAB-70 libriaries
