Cosmic Ray Helium Flux during the Period 1970-1972
Cosmic ray helium flux at the energy around 100 MeV/N was measured by four balloon flights in the summer during the period from 1970 to 1972 at Syowa Station, Antarctica, with the aid of scintillation counter telescopes. The observed helium intensity of 1972 at the energy of 100 MeV/N showed about 1...
