  The static dipole polarisability of noble gas atoms confined by impenetrable
spheres and spherical shells is studied using the B-spline random phase with
exchange approximation. The general trend in dipole polarisabilities across the
noble gas sequence shows a decrease in the dipole polarisability as the volume
of the confining impenetrable sphere is reduced and a large increase in the
dipole polarisability for confinement by impenetrable spherical shells as the
inner shell radius is increased.
