Abstract
A non-relativistic ab initio calculation of the six Judd (three-electron correlation) parameters Ti has been carried out using second- and third-order perturbation theory with a localised basis set. It is shown that the third-order perturbation contributions are significant and their inclusion considerably improves agreement between theoretical and experimental results.Keywords
