Fig. 52: Angular profiles of the nuclear scattering from 2.5 (), 10 (o), and 36 µm () unmagnetised -57Fe foils. Each angular point was measured during 30 s. The angular profile of the incident radiation is presented by the thin solid line. The bold solid line is a fit according to the theory. The dashed line shows the angular profile of nuclear small-angle scattering in -57Fe determined from the fit.
