Abstract
Calculations of P‐violating and CP‐violating dipole matrix elements for the heavy atoms Rb, Cs, Au, and Tl are described. These calculations, which are made starting from a variety of model potentials including the relativistic Hartree‐Fock potential in zeroth order, are extended to account for first‐order correlation corrections. Excitation energies, hyperfine constants, and allowed transition matrix elements are determined and compared with measurement as a control on the calculations. The spread in values of the P‐violating and CP‐violating matrix elements calculated starting from different potentials, which is a measure of the accuracy of the results, is found to be about 20% in the present work. We expect to be able to reduce this spread by including higher‐order correlation correction.
