INDUCED OF ZEEMAN COHERENCE IN AN ENSEMBLE OF CESIUM ATOMS INTERACTING WITH A 2-FREQUENCY (MICROWAVE-FIELD(RF) MAGNETIC)

Interference between Zeeman states corresponding to the forbidden magn etic-dipole transition Delta F=0, Delta m(F)=2 is reported in connecti on with the simultaneous interaction of 6(2)S(1/2) cesium atoms with a resonant microwave field and an rf field which varies at twice the La rmor frequency and is directed perpendicular to a static magnetic fiel d H-0= 0.2 Oe, (C) 1998 American Institute of Physics.
