5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM
The code was written for light- and medium-mass nuclei (or nearly magic nuclei), e.g. structural materials like iron, nickel, ... or lead. Doppler broadening is neglected for s-wave resonances, level-level and resonant-potential interference for p-, d-, ... wave levels. The sample is taken as a cylindrical disc with its axis parallel to the neutron beam. Scattering anisotropy in the c.m.s. frame is neglected. The programme accepts up to 5 TOF data sets (which may differ with respect to sample thickness and radius, energy range, instrumental resolution etc.), 200 cross section parameters (20 of them adjustable) and 512 data points (with uncertainties). Gaussian or chi-squared resolution function.
