    "abstract": "We present a new set of massless Poincar\\\u0027e group operators Hermitian with\nrespect to the $ 1 / r $ inner product space, which have quasi-plane wave\nenergy-momentum eigenfunctions having velocity $ c $ along their axis of\npropagation. These are constructed by means of a unitary transformation from a\nknown set of massless Poincar\\\u0027e group operators of helicity $ s = 0, \\pm {1\n\\over 2}, \\pm 1 ... $ The position vector $ {\\bf r} $ is the space part of a\nnull 4-vector.",
