Observation of cosmic ray positrons in the region from 5 to 50 GeVThe absolute flux of cosmic ray positrons has been measured using a balloon-borne magnet-spectrometer. Based on 193 positrons observed from 3.57 GV/c to 50 GV/c rigidity at the payload, the integral flux about 5 GeV kinetic energy at the top of the atmosphere is found to be (0.33 + or - .07)e(+)/m-sq-str-s. At the top of the atmosphere the effective energy interval for the observation is 4.5 to 64 GeV.
