    "abstract": "We investigated the electron tunneling out of a quantum dot in the presence\nof a continuous monitoring by a detector. It is shown that the Schr\\\"odinger\nequation for the whole system can be reduced to new Bloch-type rate equations\ndescribing the time-development of the detector and the measured system at\nonce. Using these equations we find that the continuous measurement of the\nunstable system does not affect its exponential decay, $\\exp (-\\Gamma t)$,\ncontrary to expectations based on the Quantum Zeno effect . However, the width\nof the energy distribution of the tunneling electron is no more $\\Gamma$, but\nincreases due to the decoherence, generated by the detector.",
