    "abstract": "In 1977, Mishra and Sudarshan showed that an unstable particle would never be\nfound decayed while it was continuously observed. They called this effect the\nquantum Zeno effect (or paradox). Later it was realized that the frequent\nmeasurements could also accelerate the decay (quantum anti-Zeno effect). In\nthis paper we investigate the quantum Zeno effect using the definite model of\nthe measurement. We take into account the finite duration and the finite\naccuracy of the measurement. A general equation for the jump probability during\nthe measurement is derived. We find that the measurements can cause inhibition\n(quantum Zeno effect) or acceleration (quantum anti-Zeno effect) of the\nevolution, depending on the strength of the interaction with the measuring\ndevice and on the properties of the system. However, the evolution cannot be\nfully stopped.",
