    "abstract": "A unified picture of nucleon antinucleon annihilation into pions emerges from\na classical description of the pion wave produced in annihilation and the\nsubsequent quantization of that wave as a coherent state. When the constraints\nof energy-momentum and iso-spin conservation are imposed on the coherent state,\nthe pion number distribution and charge ratios are found to be in excellent\nagreement with experiment.",
