Propagation of Cosmic Rays: Nuclear Physics in Cosmic-Ray Studies
The nuclei fraction in cosmic rays (CR) far exceeds the fraction of other CR species, such as antiprotons, electrons, and positrons. Thus the majority of information obtained from CR studies is based on interpretation of isotopic abundances using CR propagation models where the nuclear data and isotopic production cross sections in pand α-induced reactions are the key elements. This paper prese...
متن کاملTime Delays in Cosmic Ray Propagation
Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...
متن کاملPropagation of H and He cosmic ray isotopes in the Galaxy: astrophysical and nuclear uncertainties
Observations of light isotopes in cosmic rays provide valuable information on their origin and propagation in the Galaxy. Using the data collected by the AMS-01 experiment in the range ∼0.2–1.5 GeV nucleon−1, we compare the measurements on 1H, 2H, 3He, and 4He with calculations for interstellar propagation and solar modulation. These data are described well by a diffusive-reacceleration model w...
