    "abstract": "The quantum \"Zeno\" time of the 2P-1S transition of the hydrogen atom is\ncomputed and found to be approximately 3.59 10^{-15}s (the lifetime is\napproximately 1.595 10^{-9}s). The temporal behavior of this system is analyzed\nin a purely quantum field theoretical framework and is compared to the\nexponential decay law.",
