摘要
Accurate theoretical knowledge of the (1s2p)P-3(1)-(1s2s)S-1(0) splitting in He-like ions is demanded for future experimental studies of the nuclear spin-dependent part of the weak interaction. In this paper we perform a calculation of hyperfine structure of (1s2p)P-3(1)-(1s2s)S-1(0) within 3 <= Z <= 35, Z being the atomic number. In this Z range parity nonconservation (PNC) effects are amplified by the close energy proximity of the opposite parity levels (1s2p)P-3(1) and (1s2s)S-1(0). We find that the hyperfine structure is relevant for Z > 12, and produces splitting among the hyperfine sublevels as large as 150 meV for medium Z He-like ions (Z similar to 35).
