Neutron data evaluation of sup 2 sup 3 sup 4 U

Abstract

Consistent evaluation of sup 2 sup 3 sup 4 U measured data base is performed. Hauser-Feshbach-Moldauer theory, coupled channel model and double-humped fission barrier model are employed. Total, differential scattering, fission and (n,xn) data are calculated, using fission cross section data description as a major constraint. The direct excitation of ground state and higher band levels is calculated within rigid rotator and soft (deformable) rotator model, respectively. Average resonance parameters are provided, which reproduce evaluated cross sections in the range of 1.5 - 140 keV. This work is performed under the Project Agreement B-404 with the International Science and Technology Center (Moscow). The Financing Party for the Project is Japan
