## Abstract

The electric dipole moments (EDMs) of heavy nuclei, such as ^{199}Hg, ^{225}Ra and ^{211}Rn, can be enhanced by the Schiff moments induced by the presence of nearby parity-doublet states. Working within the framework of the maximally CP-violating and minimally flavour-violating (MCPMFV) version of the MSSM, we discuss the maximal values that such EDMs might attain, given the existing experimental constraints on the Thallium, neutron and Mercury EDMs. The maximal EDM values of the heavy nuclei are obtained with the help of a differential-geometrical approach proposed recently that enables the maxima of new CP-violating observables to be calculated exactly in the linear approximation. In the case of ^{225}Ra, we find that its EDM may be as large as 6 to 50 × 10^{−27}
