Résumé : The evolution of a quantum particle in a gaseous detector governed by the Schrödinger equation is studied by means of a simplified 3D model. The particle is assumed to interact with N excitable two-level point-like scatterers depicting the atoms. In this model, the energy loss experienced by the particle after atomic excitations is accounted for. Using the Green function method, the full wave function is uniquely determined by N times 2 to the power N complex numbers. Remarkably, the Lippmann-Schwinger equation of this multi-scattering problem can be exactly solved in a non-perturbative way. The aim is to analyze the influence of the initial microstate of the detector on the observed outcome, and to understand the mechanism of track formation in gaseous detectors.
