Abstract : We have studied how velocity-selective coherent population trapping VSCPT, adiabatic population transfer AT, and Raman transitions can be used to manipulate atoms. In particular, we have made calculations for all three methods for J to J transitions J > 1 in atoms interacting with two counterpropagating beams of opposite circular polarization σ± configuration. The momentum exchanged between the atoms and the light increases with J thus increasing the separation produced by beamsplitters and the angle of deflectors based on these techniques.
