Phys. Rev. A 66, 064102 (2002) [4 pages]Decay process accelerated by tunneling in its very early stageReceived 6 August 2002; published 9 December 2002 We examine a fast decay process that arises in the transition period between the Gaussian and exponential decay processes in quantum decay systems. It is usually expected that the decay is decelerated by a confinement potential barrier. However, we find a case where the decay in the transition period is accelerated by tunneling through a confinement potential barrier. We show that the acceleration gives rise to an appreciable effect on the time evolution of the nonescape probability of the decay system. © 2002 The American Physical Society URL:
