Abstract : Details are obtained of both the isotopic composition of cosmic rays and the rigidity cut-off of the earth's magnetosphere by examining the pulse height distributions obtained for the various cosmic ray charges in a Cerenkov detector flown aboard a high altitude balloon at a latitude where the rigidity cut-off is slightly above the threshold energy of the Cerenkov detector or with a scintillation x total energy measurement when the rigidity cut-off is below the Cerenkov threshold.
