NUMERICAL RESULTS FOR HIGH-ENERGY ELECTRON-SCATTERING CROSS-SECTIONS FROM 2-CENTER POTENTIALS

In this work we present the semiclassical formalism of relativistic el ectron scattering from two-centre potentials. The numerical results fo r the computation of cross sections have been developed and tested for the first time. Earlier results were;limited up to the calculations o f phase shifts only and thus had limitations for the application to pr actical cases. The expressions used for developing the programmes of g eneral formulae for cross sections and the different parameters, i.e. separation constants lambda(ml)(c), normalization constants N-ml(c), a ngular function S-ml(c, cos omega), expansion coefficients d(n)(c\m, l ) and phase shifts sigma(ml)(c) have also been presented. The behaviou r of the results of cross sections have been compared with those for t he case of a one-centre potential in the limit of the intercentre dist ance approaching zero.
