The departure from the exponential decay law of an unstable particle is discussed, starting from an initial state which is a general superposition of eigenstates of the Hamiltonian. By utilizing the Lee model, it is shown that the asymptotic behavior and the magnitude of the additional terms are strongiy affected by the production mechanism. Although they can never vanish exactly, these terms can be made arbitrarily small by an appropriate preparation of the initial state. A possible generalization of this result is discussed. (auth)
