Description
Energy spectrum of cosmic-ray Fe-nucleus has been measured from 4 GeV/n to beyond 100 GeV/n. The data were obtained using emulsion chambers exposed by a balloon launched from Sanriku, Japan. The energy of Fe nuclei was estimated by the opening angle method, the calibration of which was made using accelerator beams of 1.88 GeV/n Fe. The spectral index of Fe we obtained is -2.45 ± 0.04 in the range from 10 to 200 GeV/n, confirming the previous results obtained by different methods and proving the powerfulness of the opening angle method for cosmic rays.
