Abstract : The proton energy spectrum in the radiation belt has been obtained with the Injun 5 satellite for the period August 1968 through 9 February 1969 in the energy range 0.3 to 74 MeV. The most salient features of the differential energy spectrum are: in the inner belt there is a minimum at about 2 MeV; and in the outer belt the E sub o parameter is proportional to L to the power((-1.67) plus or minus 0.07). The last feature cannot be explained with the diffusion theory, at least at its present stage of development. (Author)
