  We report the results of our calculations of the atomic electric dipole
moments of cesium and thallium arising from the electron-nucleus
scalar-pseudoscalar interaction. The calculations are based on the all order
relativistic coupled-cluster theory. Electron correlation effects, particularly
in the case of thallium are of crucial importance. We obtain a new limit for
the scalar-pseudoscalar interaction by combining the result of our thallium
calculation and the measured value of the electric dipole moment of that atom.
