Abstract:

A search for the large energy fluxes of low-energy protons or positive ions 500 eV approximately equal, or E approximately equal, or 1 MeV in the earths inner radiation zone as previously reported by Freeman via the analysis of the responses of CdS crystals borne on the earth-satellite Injun 1 is reported here utilizing recent measurements of energy fluxes of protons and positive ions within the energy range 100 eV to 4.2 MeV with earth-satellites OGO 3 and Injun 4. These recent measurements provide upper limits for these proton and positive-ion energy fluxes which are less by factors of approximately 10 to 100 when compared to the Injun 1 observations during 1961. The upper limits reported here strongly indicate that large energy fluxes of low-energy protons or positive ions, approximately 50 ergscm squared-sec-sr, are not a feature of the inner radiation zone.
