Axial and triaxial shapes of Na clusters are determined by means of th
e shell-correction method.(1) The orbital paramagnetism and the diamag
netism of small Na clusters are calculated. Odd axial clusters may hav
e substantial orbital paramagnetic moments, which are quenched for tri
axial shapes. Even clusters show diamagnetism, which is maximal for sp
herical and attenuated for deformed shape.
