摘要：

We study the time evolution of an unstable particle which decays through a weak interaction. We conclude that, in general, the ''survival'' probability of any unstable particle contains a ''new'' mode inversely proportional to a certain power of time, apart from the well-known exponential decay mode which is overwhelmingly dominant. We discuss briefly this new decay mode.
