  The diverse measured data base of n+243Am was evaluated using a statistical
theory and genera-lized least squares codes. Consistent description of total,
capture and fission measured data provides an important constraint for the
inelastic scattering cross section. Important constraints for the measured
capture cross section in the 0.15-300 keV energy range come from the average
radiative and neutron S0 and S1 strength functions. The evaluated inelastic
cross sections of available evaluations are in severe disagreement, predicted
change of the inelastic cross section shape at En ~1.5 MeV is attributed to the
sharp increase of the level density of the residual odd-even nuclide 241Am due
to the onset of three-quasi-particle excitations. The influence of exclusive
(n, xnf) pre-fission neutrons on prompt fission neutron spectra (PFNS) and (n,
xn) spectra is modelled. Contributions of emissive/non-emissive fission and
exclusive spectra of (n, xnf) reactions are defined by a consistent description
of the 241Am(n, F), 241Am(n, 2n). Data file is at
