Abstract

The two slit difraction pattern, according to which the particle is both diffracted and scattered by the slits, is considered for different examples of particle-wall interactions. The calculations are developed by applying results previously obtained for incoming particle narrow in the momentun probability distribution. There results the existence of maxima superimposed to the ordinary diffraction pattern, in correspondence to the edges of the slits. The contribution of the scattering interaction is evaluated for different physical situations including the case of conducting and isolating wall. For a van der Waals-like interaction coherence is found with existing experimental data.
