Abstract
The average static dipole polarisability of the ground state of scandium is calculated. The polarisability is expressed in terms of the first-order correction in the wavefunction, due to the static electric dipole perturbation, which is determined variationally as a configuration interaction expansion. The present investigation illustrates the importance of including the configurations 3d4p5p and 3d4d5p in the wavefunction expansions. The importance of including pseudo-orbitals specifically determined to describe the polarisation of 3d is also discussed. It is also shown that it is possible to obtain a value for the average static dipole polarisability of scandium using quite simple wavefunctions.
