COSMIC-RAY ANTIPROTON SPATIAL DISTRIBUTIONS COMPUTED IN MAGNETOSPHERE
Preview AbstractThe motion of antiprotons in the Magnetosphere region is computed with some initial conditions and the spatial distributions of them are plotted. The antiprotons in the polar region are looked like coming from the outer region. Meanwhile, the antiprotons on the ISS altitude are trapped in the radiation belt. This is explained by the model that antiprotons are originated in decay particles from the antineutrons produced with the cosmic ray interactions in the atmosphere. This also shows that they are rich in the SAA region in the ISS altitudes. In order to distinguish antiprotons from protons effectively, the differences of arrival directions of them are important.
