Abstract
A new technique of x-ray spectroscopy of -mesonic atoms has been developed. The x-rays are produced when a meson undergoes transitions between Bohr orbits about nuclei of various . The mesons are produced by the Columbia University 164-in. Nevis cyclotron. The x-rays are detected, and their energies are measured to better than 1 percent accuracy (for ) using a NaI crystal scintillation spectrometer. The transition energies were measured to be 0.35, 0.41, 0.955, 1.55, 1.60, 3.50, 5.80, 6.02, and 6.02 Mev for . Special attention was paid to the Pb spectrum, and it is believed that an 0.2-Mev fine structure splitting has been observed. This is the expected splitting if the meson is a spin ½ Dirac "heavy electron" of 210 electron masses, having the expected Dirac magnetic moment and having no strong nonelectromagnetic interaction with nuclear matter.
