The intensities of electrons as measured with the SUI satellite Injun 1 during its deepest penetrations into the earth's inner radiation zone are reported for the period July 16 to August 10, 1961. The unidirectional intensity of electrons of energy greater than 40 kev was 5 x 10/sup 6/ electrons/cm/sup 2/ sec ster in a direction perpendicular to B at L = 1.22 in the magnetic equatorial plane. The corresponding omnidirectional intensity is estimated to be 1 x 10/sup 7//cm/sup 2/ sec. No temporal variations greater than the experimental uncertainty of 30 per cent were found in this region during the period of observation of this report. (auth)
