We have performed ab initio mixed-states and sum-over-states calculations of parity-nonconserving (PNC) electric dipole $(E1)$ transition amplitudes between $s\ensuremath{-}d$ electron states of Cs, Fr, ${\mathrm{Ba}}^{+},$ and ${\mathrm{Ra}}^{+}.$ For the lower states of these atoms we have also calculated energies, $E1$ transition amplitudes, and lifetimes. We have shown that PNC $E1$ …
