FULLY QUANTIZED TREATMENT OF MOLECULAR-BEAM RESONANCE

We present a fully quantal treatment of a beam of two state particles interacting with temporally oscillating potentials. A single oscillato ry potential, in resonantly coupling the two internal states, generall y entangles each with a different longitudinal momentum. Two successiv e oscillatory fields, if differentially detuned (DSOF), can couple an initially monochromatic state to a coherent momentum superposition, or alternatively may be used to detect a pre-existing momentum superposi tion.
