  • By using the method of linear regress, the relation between the cosmic ray intensity of the OULU neutron monitor and the differential fluxes of space energetic proton and ion during quiet time has been studied. The differential spectrum of interplanetary particles with high energy is also calculated through the intensity of neutron at the ground level. On the basis of the energy spectra of proton and ion, a new calculation of the differential fluxes of proton and ion with' high energy is suggested by combining the intensity of the neutron measured by OULU neutron monitor. For particular discussion, four channels (350-420 MeV, 420-510 MeV, 510-700 MeV, 〉700 MeV) on the GOES satellite and the element C on the ACE satellite are chosen as examples. Through comparison, it is concluded that the result is well consistent with the measurements. In order to prove the practicability of the method mentioned above in description of the space radiant condition,the differential As a result, it proton fluxes are is concluded that from the intensity of the ground calculated during November and December in 2006 by the method. the differential fluxes of space proton and ion may be well rebuilt neutron with this method.
