Abstract : The equivalence between continuous and discrete scattering modeling has been examined at two statistical levels: (1) the direct interaction/ladder approximation (continuous) - Twersky approach (discrete); (2) the first order smoothing approximation (continuous, discrete). Full first and second order moment equivalence has been established only at the level of the first order smoothing (or bilocal) approximation and, even then, for soft scatterers with weak transition operators.
