| Description | The primary cosmic ray proton and He spectra from 50 GeV to 2000 GeV have been measured by an ionization spectrometer flown on a balloon. At low energies, the energies of individual events are determined to within + or - 30%. At higher energies, the cascade is not fully contained within the four mean free path thick spectrometer and the problems of estimating the energies of these events are discussed. The proton spectrum continued with constant exponent = -2.7 + or - 0.1 up to energies greater than 1000 GeV. This spectrum was in agreement with the results at the low energies. There was no evidence for a spectral break at about 1000 GeV observed. |
