Cosmic ray albedo neutron decay theory

… The following two mechanisms are currently considered to be the most likely causes of the radiation belts. One is the cosmic ray albedo neutron decay hypothesis, which states that some of the neutrons produced in the atmosphere by cosmic rays decay into protons, electrons, and neutrons on their way to the magnetosphere and are captured by the Earth's magnetic field. This mechanism cannot explain the formation of the entire radiation belt, but it is thought that the high-energy component of the inner belt is due to this mechanism. …

… 放射線帯の成因としては,現在次の二つの機構が有力視されている。その一つは,宇宙線アルベド中性子崩壊説といわれるもので,宇宙線によって大気中につくられた中性子の一部が磁気圏へ飛び出す途中で,陽子と電子と中性微子に崩壊し地球磁場に捕捉されるという考えである。この機構では全放射線帯の生成を説明できないが,内帯の高エネルギー成分はこの機構によると考えられている。…
