Abstract
We propose an experiment to determine the density operator for the lon gitudinal quantum state of an atomic beam. The method is based on tomo graphic reconstruction of the Wigner function via a set of measured pr obability distributions for the phase-space rotated position operator. The time evolution of the Wigner function in free space effectively p erforms the required phase-space rotation. We propose a state-selectiv e time-dependent technique for measuring longitudinal probability dist ributions.
