Abstract
We compute, in the perturbative model of Johnson and Low, the one-meson-to-vacuum matrix element of the equal-time commutator of the charge density of a vector current and a scalar density. A gradient term is found. Consequences of this result for the dimensionality of the current components are discussed.Keywords
