Solar Modulation of the Galactic Electron and Proton Intensity near the Activity Minimum of 2009

详细

A model of galactic cosmic ray modulation is presented that satisfactorily describes long-period variations in the intensity of the proton and electron components in the waning phase of the solar activity of the 23rd cycle (2006–2009). A distinctive feature of the model is its description of the temporal behavior of energy spectra of both electrons and protons at the same fixed values of model parameters. Model calculations are compared to measurement data obtained on the PAMELA spectrometer for spectra of the proton and electron components of galactic cosmic rays.
