The effects arising from atomic recoil during stimulated emission or absorption can play a dominant role in the pump¡ªprobe spectroscopy of a sub¡ªDopplers or sub¡ªrecoil2 cooled gas. The atomic recoil that accompanies spontaneous emission (SpRE) can also lead to new physical effects. One such effect, recoil induced optical Faraday rotation (RIOFR), is the subject of this contribution. We have been able to isolate a case in which the rotation of a probe field’s plane of polarization originates solely as a result of SpRE. To observe this rotation, one chooses the probe field unit polarization vector e’ = x and wave vector k’ a z, and the pump field polarization vector e in the (x,z) plane and wave vector k a y. In the absence of recoil there is no Faraday rotation for this geometry.
