Parity violation effects with doubly excited states in heavy Li-like ions

Quasidegenerate states of different parity for heavy Li-like ions are studied to search for the enhancement of the parity non-conservation (PNC) effects. The energies of the states \left (1 {s} 2 {s} n\kappa \right )_{1/2} and \left ( 1 {s} 2 {p}_{1/2} n\kappa \right )_{1/2} with κ = ± 1 and 4 ⩽ n ⩽ 7 are evaluated in the range Z = 54-100. The PNC admixing parameter has been calculated for the states with n and κ, which seem most promising for increasing the PNC effect. The PNC effect is evaluated for the process of dielectronic recombination of a polarized electron with a helium-like ion.
