Abstract A proposal is put forward for an estimate of the duration of a transition between atomic states. The proposal rests on the consideration that a resonance of the atomic electron with modes of the zero-point radiation field of Compton's frequency is at the core of the phenomenon. The theoretical result, given essentially by the expression ( α ω C ) − 1 , where α is the fine structure constant and ω C the Compton angular frequency for the electron, lies well within the range of the recently experimentally estimated values of the order of attoseconds ( 10 − 18 s).

量子跳跃有多快？

摘要 提出了估计原子态间跃迁持续时间的建议。该提议基于这样的考虑，即原子电子与康普顿频率的零点辐射场模式的共振是该现象的核心。理论结果主要由表达式 (α ω C ) − 1 给出，其中 α 是精细结构常数，ω C 是电子的康普顿角频率，完全在最近实验估计值的范围内阿托秒（10 - 18 秒）。
