N2 - A previous calculation of the size dependence of the conduction-electron spin-resonance g shift for a small particle of sodium with cubic shape is extended to the case of a particle with spherical shape. Within a model where the conduction-electron wave functions are approximated by single orthogonalized standing waves, it is found that one of the major size-dependent contributions to the g shift displays, for a spherical particle, the same qualitative size dependence as was obtained previously for a cubic particle. Specifically, we find that this term can be written as g(R)=[1-(aR)]g(), where a is the lattice constant, is a parameter of the order of unity, R is the radius of the spherical particle, and g() is the bulk g shift.
