SPIN MAGNETIC FORM-FACTORS FOR LITHIUM AND ITS ISOELECTRONIC SERIES IN POSITION AND MOMENTUM-SPACE

For the lithium atom, spherically averaged total and magnetic form fac tors, F(k) and M(k), and internally folded densities, B(s) and Q(s) ha ve been calculated from highly accurate configuration interaction wave functions. Their general functional behaviour is analysed together wit h those from the lithium isoelectronic series (Be+ to Ne7+). The influ ence of electron correlation on these properties is investigated by co mparisons with calculations obtained from Hartree-Fock wavefunctions.
