    "abstract": "We study the short-time and medium-time behavior of the survival probability\nin the frame of the $N$-level Friedrichs model. The time evolution of an\narbitrary unstable initial state is determined. We show that the survival\nprobability may oscillate significantly during the so-called exponential era.\nThis result explains qualitatively the experimental observations of the NaI\ndecay.",
