Progress on high precision calculations for the ground state of atomic lithium

Abstract

Progress on high precision calculations for the ground state of atomic lithium is reviewed. The following properties are considered: upper and lower bounds to the nonrelativistic ground state energy, the specific mass shift, the transition isotope shift, relativistic corrections to the ground state energy, the Lamb shift, the ionization potential, the electron affinity, the hyperfine coupling constant, the nuclear magnetic shielding constant, the diamagnetic susceptibility, several polarizability factors, shielding constants, oscillator strength sums, the electron density and spin density, intracule functions, moments 〈 r i n 〉 and 〈 r ij n 〉 and form factors. A discussion is also given on some convergence considerations as they apply to high precision calculations on the lithium atom.
