Abstract
An exact quantum solution is obtained for the problem of Gaussian wave packet motion in an anharmonic potential. Wave-packet evolution is des cribed by means of an autocorrelation function. The solution is expres sed via the theta function with time-dependent argument and parameter. A simple physical analogy is proposed for the wavepacket motion. The problem of calculating the width of the wavepacket ''revival zones'' i s considered.
