We perform calculations of the CP-violating atomic and molecular electric\ndipole moments (EDM) induced by the interaction of the nuclear Schiff moments\nwith electrons. EDM of atoms Eu, Dy, Gd, Ac, Th, Pa, U, Np and Pu are of\nspecial interest since they have isotopes with strongly enhanced nuclear Schiff\nmoments caused by the octupole nuclear deformation or soft octupole vibration\nmode. These atoms have open 4f or 5f shells making the calculations\ncomplicated. We use our special version of the configuration interaction method\ncombined with the many-body perturbation theory method adopted for open f-shell\ncase. To validate the method we perform similar calculations for simpler atoms\n(Xe, Hg, Tl+, Pb, Pb++, Rn, Ra) where some earlier results are available. In\naddition we present the estimates of the CP-violating nuclear spin - molecular\naxis interaction constants for molecules which may be of experimental interest\nincluding AcF, EuN, ThO, PbO and TlF. We also present updated values of the\nnuclear Schiff moments and atomic and molecular EDM expressed in terms of the\nCP-violating pi-meson - nucleon interaction constants g_0,g_1, g_2, QCD\nparameter theta and quark chromo-EDMs. The results may be used to test\nCP-violation theories and search for axion dark matter in atomic, molecular and\nsolid state experiments.\n
