一个不稳定系统的振荡衰减

Oscillating decay of an unstable system

I. Antoniou, E. Karpov, G. Pronko, E. Yarevsky

摘要:

在$N$ -水平Friedrichs模型框架下研究了生存概率的短期和中期行为。确定了任意不稳定初态的时间演化。我们表明,生存概率可能会振荡显着在所谓的指数时代。这一结果定性地解释了NaI衰变的实验观察。

英文摘要:

We study the short-time and medium-time behavior of the survival probability in the frame of the $N$-level Friedrichs model. The time evolution of an arbitrary unstable initial state is determined. We show that the survival probability may oscillate significantly during the so-called exponential era. This result explains qualitatively the experimental observations of the NaI decay.
