    "abstract": "We examine an analytical expression for the survival probability for the time\nevolution of quantum decay to discuss a regime where quantum decay is\nnonexponential at all times. We find that the interference between the\nexponential and nonexponential terms of the survival amplitude modifies the\nusual exponential decay regime in systems where the ratio of the resonance\nenergy to the decay width, is less than 0.3. We suggest that such regime could\nbe observed in semiconductor double-barrier resonant quantum structures with\nappropriate parameters.",
