Summary
We consider a simple one-dimensional system consisting of two particles interacting with a δ-potential and we discuss a rigorous derivation of the asymptotic wave function of the system in the limit of small mass ratio. We apply the result for the explicit computation of the decoherence effect induced on the heavy particle in a concrete example of quantum evolution.
