    "abstract": "Classical electromagnetic radiation from quantum currents and densities are\ncalculated. For the free Schrodinger equation with no external force it\u0027s found\nthat the classical radiation is zero to all orders of the multipole expansion.\nThis is true of mixed or pure states for the charged particle. It is a\nnon-trivial and surprising result. A similar result is found for the\nKlein-Gordon currents when the wave function consists of only positive energy\nsolutions. For the Dirac equation it is found that radiation is suppressed at\nlower frequencies but is not zero at all frequencies. Implications of these\nresults for the interpretation of quantum mechanics are discussed.",
