Hyperfine Splitting of Low-Lying Levels in Heavy Li-Like Ions

Abstract

The magnetic dipole and the electric quadrupole hyperfine splitting in heavy Lilike ions is calculated for the (1s)22p1/2 and (1s)22p3/2 states. The numerical results include the one-electron contributions as well as the interelectronic-interaction correction of order 1/Z, calculated within a rigorous QED approach. Total hyperfine splitting energies are presented for heavy Li-like ions in the range Z = 49–83.
