Abstract
We analyze the short-rime behavior of the survival probability in the frame of the Friedrichs model for different form factors. We have shown that thi s probability is not necessarily analytic at the time origin. The time when the quantum-Zeno effect could be observed is found to be much smaller than usually estimated. We have also studied the anti-Zeno period and have esti mated its duration.
