Propagation of Cosmic-ray Nucleons in the Galaxy

  title={Propagation of Cosmic-ray Nucleons in the Galaxy},
  author={A. W. Strong},
We describe a method for the numerical computation of the pro pagation of primary and secondary nucleons, primary electrons, and secondary positrons and electrons. Fragmentation and energy losses are computed using realistic distributions for the interstellar gas and radia tion fields, and diffusive reacceleration is also incorpora ted. The models are adjusted to agree with the observed cosmic-ra y B/C and10Be/9Beratios. Models with diffusion and convection do not account well for the observed… CONTINUE READING
