摘要

Investigations of the hyperfine structure of the 1s(2)p (2)P state of lithium using configuration interaction wavefunctions, with a view to understanding which configurations are important. In addition to single particle replacements 1s to 2s, 1s to 3d, the replacement 2p to np must also be included, even though to first-order its effect is negligible (Brillouin's theorem). The inclusion of two-particle replacements makes the coefficients of the 1s2np configurations non-zero. It is this effect which almost entirely accounts for the modification of the orbital term al from its Hartree-Fock value. The values of the magnetic hyperfine constants A3/2 = -3.1 MHz, al/2 = 46.2 MHz, in agreement with experiment, were obtained. (Author)
