Abstract: Institute of Physical and Chemical Research (RIKEN), Saitama, Japan Results of measurements of the absolute values and long term temporal evolution of the spatial distribution of trapped He ion fluxes of 3.2 - 9.2 MeV/nucleon energy at L < 4 obtained by the OHZORA satellite are reported. The annually averaged radial profile exhibits one persistently present peak at L = 1.3 - 1.5 as well as very significant transient trapped fluxes at L = 1.4 - 4.0 during the period 1984-1986. Together the absolute values of the fluxes measured by OHZORA and S72-1, SAMPEX, and CRRES spacecrafts may approximately be described by a power spectrum with index of -8.0±1.0 at L = 1.9-2.3 within the energy range of 3 - 100 MeV/nucleon.
