    "abstract": "Accurate QED evaluations of the one- and two-photon interelectron interaction\nfor low lying two- and three-electron configurations for ions with nuclear\ncharge numbers $60\\le Z \\le 93$ are performed. The three-photon interaction is\nalso partly taken into account. The Coulomb gauge is employed. The results are\ncompared with available experimental data and with different calculations. A\ndetailed investigation of the behaviour of the energy levels of the\nconfigurations $1s_{1/2}2s_{1/2} {}^1 S_0$, $1s_{1/2}2p_{1/2} {}^3 P_0$ near\nthe crossing points Z=64 and Z=92 is carried out. The crossing points are\nimportant for the future experimental search for parity nonconserving (PNC)\neffects in highly charged ions.",
