 note = {P(論文), To study cosmic protons, helium and CNO components (E=100-500MeV/n) together with Hard X-rays (E=30-120keV) of auroral, solar and/or cosmic origins, the Polar Patrol Balloon no. 6 (PPB#6) was launched from Syowa Station, Antarctica on January 5,1993 by the 34th Japanese Antarctic Research Expedition. PPB#6 moved westward by 1.5 circumpolar rounds over Antarctica covering 6-13g/cm^2 atmosphereic depth and 63°-70°S geographic latitude. The cosmic radiation intensity was measured by detector system on PPB#6. This paper shows the cosmic proton intensity as a function of the geomagnetic rigidty and the proton spectra at invariant latitude of 55°, 80°, and at the cusp latitude.},
