| Abstract: | A generalization is presented in this article of the method of tight coupling used to describe particles with extension within the framework of the scalar-field theory with single-power law interaction. For the coupling λ?4 an estimate is found by variational methods for the energy spectrum of lower single-particle excitations. |
