Abstract:
Energetic particles from the cosmic radiation, coming from outer space, enters in the Earth’s atmosphere. The primary cosmic ray particles collide with the atomic nuclei of the Earth’s atmosphere, generating air showers with short-lived secondary cosmic ray particles. Some basic features of the cosmic rays: the energy of the particle, arrival direction and type of the primary particle are estimated from study of extensive air showers. The latitude dependence of the cosmic ray intensity seem to be most readily explained by the fact that, the proton fluxes will be strongest at the poles than that at the equator. In conclusion, because of small deflection in the magnetic fields, arrival directions of the primary cosmic ray proton say something both about the propagation of the cosmic rays and their sources.
