On the Wave Equation of Meson

Up to the present much work on meson theory has. been done by considering it as a field theory, and the equation of meson as a field equation. This situation has its origin in the fact that the meson was found originally as a field of the heavy particles. However, if we restrict ourselves to the problems of the interaction between the meson and the electromagnetic field, it seems more adequate to treat the meson equation in the form of a wave equation just like the cases of other charged particles(1), i.e. electron, positron and proton. Using the usual field equation for the meson as a wave equation, Laporte(2) has developed this stand point and calculated the elastic scattering of meson by a static electric field as a one body problem. The authors themselves, when they were engaging in the establishment of the vector meson theory, tried to write the meson equation in the form analogous to Dirac's electron equation. But before they could finish this task, certain circumstances prevented one of the authors
