Non-relativistic variational calculations of atomic properties in Li-like ions: Li I to O VI

The multiconfiguration Hartree-Fock method is used to calculate wavefunctions in the infinite nuclear mass limit for the terms 2s ²S, 2p ²P^o, 3s ²S, 3p ²P^o, 3d ²D and 4s ²S of lithium-like ions (3⩽Z⩽8). Transition data, isotope shift parameters and hyperfine structure electronic contributions involving the six terms of the six ions are evaluated ab initio and compared with the most recent observations and other theoretical calculations when available. The isotopes ^7,6Li I, ^11,10,9,7Be II, ^11,10B III, ^14,13,12C IV, ^15,14N V and ^18,17,16O VI are considered in the analysis of the mass isotope shifts.
