摘要：

The quantum "Zeno" time of the 2P-1S transition of the hydrogen atom is computed and found to be approximately 3.59 x 10(-15) s (the lifetime is approximately 1.595 x 10(-9) s). The temporal behavior of this system is analyzed in a quantum field theoretical framework and compared to the exponential decay law. (C) 1998 Published by Elsevier Science B.V.
