Abstract
The factorisation method is used to analyse the motion of wavepackets in symmetric, confining, one-dimensional reflectionless potentials. We calculate the quantal time advance and compare it to the classical limit. It is proven that the broadening of wavepackets is delayed when they move over the potential well.
