Abstract

It is well known that the vector theory of the meson1 contains a fundamental length in the interaction of mesons with protons and neutrons determined by the fact that the mass of the meson appears explicitly in the denominator of some of the interaction terms. This circumstance has the result that in those elementary processes in which the momentum change is large compared with mc, m being the mass of the meson, the interaction becomes very large, leading to Heisenberg explosions, and to greater divergences in some second-order effects than is the case in radiation theory. This has led Heitler2 and others to the view that the meson theory in its present form is quite incorrect for meson energies larger than about mc 2, and Heisenberg3 to the position that quantum mechanics is competent to deal accurately with only those elementary processes in which the condition4 due to Wataghin, is satisfied, Epsilon and p being the initial and final energy and momenta of a particle concerned in the process, and ro a fundamental length of the order mc. The purpose of this note is to bring forward an argument which, it seems to me, shows first that the limitation of quantum mechanics by the condition (1), if true, cannot be based on the explosions as derivable from the theory of the meson, and secondly, to throw some doubt on (1) itself as a limit to the correctness of quantum mechanics.
