An experiment to measure energetic neutrons and gamma rays in space was launched in the first Indian scientific satellite, Aryabhata, on April 19, 1975. From this experiment, the first measurements in space of the earth's albedo flux of neutrons of energy between 20 and 500 MeV have been made; the values obtained for two mean geomagnetic vertical cut-off rigidities of 5.6 and 17.0 GV are (6.3 plus or minus 0.4) x 10 to the -2nd and (1.4 plus or minus 0.3) x 10 to the -2nd neutrons/sq cm/s, respectively. These measurements confirm that protons arising from cosmic ray albedo neutron decay, can adequately account for the protons in the inner radiation belt. Observations on gamma rays of energy between 0.2 and 24 MeV have enabled the determination of the total background gamma ray flux in space as a function of latitude.
