In this case, an extremely restrictive condition is assumed in which the incoming wave is purely coherent, assuming that it is feasible to produce a series of particles in the same quantum state (equal mass, with the same impact parameter, same amplitude, same phase) .
The arrangement of two slits, modeled as two Gaussians of width δ separated by a distance δ/a= 0.1, are reached by a pure Gaussian state of width d and impact parameter b/a = −1 / 2.
In order to analyze different results (interference patterns visible or not) it is proposed to vary the width of the pure-state Gaussian wave packet. It is recommended to test the following values: d / a = 10, 1, 0.75, and 0.25.
