Popis:	We present the first measurement of the longitudinal density matrix of a matter-wave beam. Usinga unique interferometric scheme, both the amplitude and phase of off-diagonal density matrix elementswere determined directly, without the use of traditional tomographic techniques. The measureddensity matrix of a doubly amplitude modulated atomic sodium beam compares well with theoreticalpredictions.
