%0 Journal Article %A Luis Aina, Alfredo %A Sánchez Soto, Luis Lorenzo %T Determination of atom-field observables via resonant interaction %D 1998 %@ 1050-2947 %U https://hdl.handle.net/20.500.14352/59703 %X We find the observables that-can be determined by two practical schemes based on atom-field resonant interaction. In the first example, the interaction is followed by photon-number and atomic-population measurements. In the second scheme the directly measured quantity is the atomic deflection. In particular, we show that they provide the measurement of the atom-field relative phase. When the initial field state is known, the atomic density matrix can be reconstructed. %~
