Model calculation of the size dependence of the CESR g shift in a small sodium particle

The size dependence of the CESR g shift is calculated for a model Na cube of side L, employing single orthogonalized standing waves for the conduction electron wave-functions. The principal result of this calculation is that the absolute value of δg(L) decreases with decreasing particle size, in contrast with the predictions made for small L by Kawabata on the basis of a model with diffuse surface scattering boundary conditions.
