Temporal behavior and quantum Zeno time of an excited state of the hydrogen atom
Abstract
The quantum "Zeno" time of the 2P-1S transition of the hydrogen atom is computed and found to be approximately 3.59 10-15s (the lifetime is approximately 1.595 10-9s). The temporal behavior of this system is analyzed in a purely quantum field theoretical framework and is compared to the exponential decay law.
