费米“黄金法则”与非指数衰变

Fermi's "Golden Rule" and Non-Exponential Decay

C. Dullemond

摘要:

研究的是简单模型中不稳定状态的行为,但这些模型是自然界中发生的情况的现实表示。它表明,一个非指数衰减模式将最终占主导地位的衰减,由于能量的下限。当时间趋于无穷大时,存活率比时间的平方反比更快地接近零。

英文摘要:

A study is made of the behavior of unstable states in simple models which nevertheless are realistic representations of situations occurring in nature. It is demonstrated that a non-exponential decay pattern will ultimately dominate decay due to a lower limit to the energy. The survival rate approaches zero faster than the inverse square of the time when the time goes to infinity.
