AB The quadrupole polarizabilities and nuclear shielding factors of the helium sequence are calculated to high accuracy by a combination of variational and perturbation methods. The results suggest that the simpler methods usually employed are satisfactory for computing polarizabilities but less so for computing shielding factors.
