摘要：

We use (nonconservative) dynamical semigroups to investigate the decay law of a quantum unstable system weakly coupled with a large environment. We find that the deviations from the classical exponential law are small and can be safely ignored in any actual experiment. (C) 1998 Published by Elsevier Science B.V. All nights reserved.
