Energetic heavy ions with 20∼200 MeV/nucleon in the radiation belts have been observed by Heavy Ion Telescope (HIT) onboard TSUBASA satellite. The data observed during quiet periods in the outer region of radiation belt indicate that the relative abundance for major elements are similar to that of primary nuclei in galactic cosmic rays obtained by ACE/CRIS experiment, in particular for the ratio of 22Ne/20Ne, while the absolute intensities there were less than that obtained by ACE/CRIS. On the other hand, in the inner region of radiation belt near the earth, both energetic 3He and 4He isotopes were enhanced, in particular for 3He, however, no energetic heavy ions except for energetic nuclei as Li-B, N and Ar were observed. Thus the charge and mass composition of heavy ions is essential to our consideration of possible sources and behavior of energetic heavy ions trapped in the radiation belt.
