We examine the revival features in wave-packet dynamics of a particle confined in a finite square-well potential. The possibility of tunneling modifies the revival pattern as compared to an infinite square-well potential. We study the dependence of the revival times on the depth of the square well and predict the existence of superrevivals. The nature of these superrevivals is compared with similar features seen in the dynamics of wave packets in an anharmonic-oscillator potential. 1999 The American Physical Society.
