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 ( $\sigma^{\pm}$ 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.
