We report an observation of the long-term evolution of a radially localized
electronic wave packet formed by the coherent superposition of Rydberg
states of atomic potassium. Initially, the wave packet can be described
classically. Subsequent dephasing of the discrete states in the
superposition leads to a loss of spatial localization so that the evolution
can no longer be described classically. However, the wave packet revives
at a later time. Theory and experiment show good agreement including an
accurate measurement of the phase shift of the wave packet on revival.
