SPATIAL ASYMMETRY OF LOW ENERGY POSITRONS IN $pi$$sup +$ - $mu$$sup +$ - e$sup +$ DECAY (in Russian)
S>Studies were made of published data on the spatial distribution asymmetry of low-energy- positrons in pi /sup +/ - mu /sup +/ - e/sup +/ decays. Standard NIKFI-R emulsion was used for measuring the spectrum of 1102 particles at a = 0.077. The slow electron spectra contained 345 particles with the epsilon = 0.6 energy at a = 0.077; the complete spectrum contained 565 positrons at a = 0.28. The datu were used to determine the ratio of positrons emitted forward and backward ( delta = N/sub f/ -N/sub b/ )/(N/sub f/ + N/sub b/). The values of N/sub f/ and N/sub b/ in the energy ranges 0 to 0.3, 0.3 to 0.6, 0.6 to 0.8, 0.8 to 1.0, and > 1.0 and the excess of delta are plotted and tabulated. The asymmetry drops sharply at the transition from the edge of the spectrum to low energies and it is practically eliminated at epsilon < 0.5. (R.V.J.)
