Query: Fields and Quantum Mechanics   The quantum field theories (QFT) constructed in [1,2] include phenomenology
of interest. The constructions approximate: scattering by $1/r$ and Yukawa
potentials in non-relativistic approximations; and the first contributing order
of the Feynman series for Compton scattering. To have a semi-norm, photon
states are constrained to transverse polarizations and for Compton scattering,
the constructed cross section deviates at large momentum exchanges from the
cross section prediction of the Feynman rules. Discussion includes the
incompatibility of canonical quantization with the constructed interacting
fields, and the role of interpretations of quantum mechanics in realizing QFT.
