Temporal behavior and quantum Zeno time of an excited state of the hydrogen atom
arXiv:quant-ph/9905017 · doi:10.1016/S0375-9601(98)00144-3
Abstract
The quantum "Zeno" time of the 2P-1S transition of the hydrogen atom is computed and found to be approximately 3.59 10^{-15}s (the lifetime is approximately 1.595 10^{-9}s). The temporal behavior of this system is analyzed in a purely quantum field theoretical framework and is compared to the exponential decay law.
