On the Use of the Tomonaga Intermediate Coupling Method in Meson Theory

Abstract

It is shown that the Tomonaga method for obtaining an intermediate coupling approximation in meson theory can be formulated very simply and will in general give accurate results in the limits of weak and strong coupling. The problem of nuclear forces in the charged scalar theory is studied. The ratio of ordinary to exchange forces is given as a function of the coupling strength. Photo-meson production is studied in the intermediate coupling region for both charged scalar and charged pseudoscalar theories. The method is seriously limited in that nucleon recoil is neglected.
