Weak- and hyperfine-interaction-induced 1s2s 1S0→1s2 1S0 E1 transition rates for the isoelectronic sequence of Helike ions have been calculated using the multi-configuration Dirac-Hartree-Fock (MCDHF) and relativistic configuration interaction methods. The results should be helpful for the future experimental investigations of parity non-conservation effects.

Keywords:  parity non-conservation effect      hyperfine interaction      MCDHF method
