In the frame of a general master equation, we investigate the condition for the propagation of pure-state wave packets conditioned to the gain-loss competition between the different components. If a perturbative approach is adopted, it is shown that the hamiltonian type of evolution is destroyed within the microscopic time-scale, thus inhibiting the possibility of simulating the motion via a frictional Schrödinger equation as frequently undertaken. © 1983.
