Abstract
A general expression is derived for the (paramagnetic) shielding factor for a nuclear spin embedded in a d-dimensional noninteracting electron gas and a parabolic quantum dot. We find that for d = 2 the Knight shift has no in trinsic magnetic field dependence and that for the quantum dot the shift is negligible unless the nuclear spin is near the centre.
