The zero-mode spectrum of the spin-3/2 wave operator is examined in n dimensions. The authors prove that there are no non-trivial transverse modes on any compact two-dimensional Riemannian space with positive curvature nor on any standard n sphere for n>1. Such results reinforce the need for non-minimal operators to describe the physical fermion spectra in Kaluza-Klein phenomenology.
