Abstract
Theoretical implications of the suggestion that the observed nucleon electromagnetic form factors indicate the existence of a nucleon "core" are discussed. On the basis of physical arguments concerning the nature of such a core, it is shown that, for the neutron, both the charge form factor, , and the magnetic form factor, , must vanish as , the invariant momentum transfer, increases without limit. On the other hand, for the proton and , where is the wave function renormalization constant for strong interactions, which is a measure of the probability of the "core state." In terms of the Dirac form factor, , and the Pauli form factor, , these results read , , and for both neutron and proton. The results for are the same as those obtained by Hiida, Nakanishi, Nogami, and Uehara. The other result implies the existence of a relationship which may be used to eliminate one parameter in the analysis of . The generality of the interpretation of and as Fourier transforms of distributions of charge and magnetization, respectively, is demonstrated in the Appendix.
