Using the Bixon–Jortner Hamiltonian as a model of a discrete system, we compare the decay of a prepared state into an infinite, discrete manifold with similar decays into large but finite systems. We find that the differences between these two types of systems are strongly related to the number of manifold states. © 1995 John Wiley & Sons, Inc.
