Correlations between nuclear Schiff moment and electromagnetic measurements

NUCLEAR MOMENTS ¹²⁹Xe, ¹⁹⁹Hg; calculated the nuclear Schiff moments induced by the nucleon electric dipole moment using large-scale shell model; deduced the next-to-leading-order contribution arises from parity and time-reversal violation in the nucleus, that these secondary effects do not induce any significant disturbance to the correlation. Comparison with available data.
