It is proposed to measure the electric dipole moment (edm)                 of the cesium atom and thereby measure the edm of the electron.                 The existence of an edm for the electron would imply a violation                of time-reversal invariance.  The basic principle of the                        experiment is to spin polarize the ground state of cesium and to                search for a precession of that polarization in an applied                      electric field.  High polarizations and relatively long lifetimes               can be obtained using optical pumping techniques and well                       designed cells.  With precision polarization analyzing                          techniques, it is possible to observe very small precessions.  In               the present experiment an electron edm of about 10 (E-25) e-cm                  should be detectable.  These results will place interesting                     constraints on super-symmetric gauge theories and other new                     unified models.
