Abstract

Experiments were done to determine the (238)U(n,n') cross section for incoming neutron energies from 1 to 4 MeV and excitation energies between 0.5 and 1.5 MeV. Neutrons are produced by the T(p,n)(3)He reaction at the 7 MV Van de Graaff accelerator. The neutron detectors are NE213 liquid scintillators placed at angles of 55 , 90 and 125 . Neutron time of flight and pulse height spectra are recorded. Pulse shape analysis is applied. The normalization of the data is done relative to the elastic scattering cross section of (nat)C for energies less than 2 MeV and to the well known n-p cross section at higher energies. Preliminary quantitative results are presented. Comparisons are made with data available in literature, with current evaluated data files and with models calculations.
