1939Nature 8 July 78/1 The most important problem is the construction of a classical model of the heavy mass by means of a mesonic field in the same manner as the electronic mass is built up from an electromagnetic field. 1953Physical Rev. XCII. 801/2 The use of the µ- meson as a nuclear probe is possible because the mesonic orbits are much closer to the nucleus than the corresponding electron orbits. 1954Ibid. XCVI. 1145 The effects of vacuum polarization on the energy levels of π and µ mesonic atoms are computed. 1959Chambers's Encycl. XIII. 241/2 The measurement of mesonic mass is very difficult. 1968M. S. Livingston Particle Physics vi. 122 The first estimate of the mass of the muon came from studies of the ionization density of the tracks of mesonic particles in cloud chamber photographs of cosmic rays. |
