Nuclear interactions of CR with space plasma matter

1.3.1. Cross sections, paths for absorption, and life time of CR particles relative to nuclear interactions in space plasma

Nuclear interactions of CR particles take place during processes of CR generation (in supernova remnants, stellar coronas, in the interstellar space and so on) and propagation in space plasma. These interactions lead to fragmentation of CR nuclei and absorption. Cross sections 7j and transport paths A for absorption of different nuclei of CR in the interstellar plasma (93% of hydrogen and 7% of helium) according to Ginzburg and Syrovatsky (1966) is shown in Table 1.3.1.
