摘要 我们展示了如何用稳定渐近态来定义不稳定粒子的状态。这个一般定义用于讨论和解决与非衰变幅度的短时和大时行为有关的一些老问题。
Abstract We show how the state of an unstable particle can be defined in terms of stable asymptotic states. This general definition is used to discuss and to solve some old problems connected with the short-time and large-time behaviour of the non-decay amplitude.
