    "abstract": "Under certain assumptions it is shown that the decay of level 2 of a\nthree-level system onto level 1 is slowed down because of the further decay of\nlevel 1 onto level 0. It is argued that this phenomenon may be interpreted as a\nconsequence of the quantum Zeno effect. The reason why this may be possible is\nthat the second decay (or accompanying photon radiation) may be considered as a\nsign of the transition 2 -\u003e 1 so that during the first transition the system is\nunder continuous observation.",
