Abstract
The motion of a classical test particle, which evolves deterministically in a potential field and where at a given rate its velocity is randomized, is investigated. A path integral approach is used to find exact solutions for the free and harmonically bound particles. Both the exact solution and numerical solution for a nonlinear case show large deviations from the diffusion limit.
