Differential cross sections of elastic neutron-proton scattering have been
measured far the energy range from 200 MeV to 580 MeV. The angular interval
for the detection of the recoiling proton ranges up to 48 degrees in the l
aboratory system. This corresponds to an interval of the scattering angle f
rom 80 degrees to 180 degrees in the centre-of-mass system. For absolute no
rmalization the simultaneously measured np --> d pi degrees reaction was us
ed above 280 MeV. The charged pi NN coupling constant has been determined t
o f(pi np)(2) = 0.076+/-0.001.
