A question worth addressing in theories of the nucleus derived from field theories is the determination of the parameters which enter into the theory. If a parameters is dimensionless, as is the nucleon-nucleon pi meson strong interaction coupling constant, it is conceivable that is can be determined using field theory. The coupling constant might then be determined by a condition placed on the functions which describe the solution. In this work it is shown that such a solution cannot exist. Several interesting and important quantum field theories must contain the coupling constant in the boundary conditions. The theories considered in the present discussion include quantum electrodynamics of spin-1/2 fermions and gauge field theories. 5 refs.
