**Abstract:**

*A model for composite systems consisting of fermions with internal degrees of freedom interacting via intermediate vector bosons (IVB) is constructed. Highly localized, low-mass bound states are found in the Hartree-Fock approximation. The dependence of these states as function of the coupling constant and vector boson mass is investigated. In the limit of infinite vector boson mass the interaction is described by Fermi-type contact forces. © 1990 American Institute of Physics.*
