Results are given of studies made with 10,000 cases of ( pi -- mu ) decay by pi /sup +/ mesons stopped in emulsion bombarded by a synchrotron beam. The angular projection of the mu /sup +/ meson initial motion and the direction of the pi meson beam were measured. The coefficient of asymmetry for the angular distribution was 0.048 plus or minus 0.020. Corrections based on the systematic re-evaluation of processes in the emulsion produced a corrected coefficient of assymetry 0.009 plus or minus 0.018, which indicates that the angular distribution of mu /sup +/ meson from ( pi -- mu ) decay of stopped pi / sup +/ mesons is isotropic.
