Abstract

The time evolution of an unstable quantum system coupled with an external "measuring" apparatus is investigated. A quantum Zeno effect (hindered decay) or an inverse quantum Zeno effect (accelerated decay) may take place, depending on the features of the coupling and the response time of the apparatus. The transition between the two regimes is analyzed.
