Neutron and proton nuclear data evaluation for sup 2 sup 3 sup 5 U and sup 2 sup 3 sup 8 U at energies up to 250 MeV

Basic features of nuclear data evaluation for uranium isotopes sup 2 sup 3 sup 5 U and sup 2 sup 3 sup 8 U at intermediate energies are described. The coupled channel optical model was used to obtain total cross section, reaction cross section, angular distributions and transmission coefficients. The direct, pre-compound and evaporation models were used to describe neutron and charged particles emission from excited nuclei. The neutron data evaluated were combined with JENDL-3.3 data below 20 MeV to obtain a full data set in the whole energy range between 10 sup - sup 5 eV an 250 MeV. Evaluation of the proton data has been done at energies from 1 to 250 MeV.
