Cosmic rays constitute a super-thermal gas of charged particles magnetically confined within the Galaxy. Cosmic ray nuclei and electrons are a principal source of the diffuse γ-ray background in the Galaxy. Thus, understanding diffuse γ-ray production is directly related to understanding cosmic ray propagation in the Galaxy.

Theoretical predictions for cosmic ray secondary antiprotons
Advances in Space Research, 1997Abstract We calculate the flux of secondary antiprotons produced by cosmic rays during propagation in the interstellar medium. We illustrate with several examples how the resulting antiproton to proton ratio as measured depends on the assumed primary spectrum and on propagation.

<p><span>Secondary cosmic-ray neutrons may be effectively used as a proxy for environmental hydrogen content at the hectare scale. These neutrons are generated mostly in the upper layers of the atmosphere within particle showers induced by galactic cosmic rays and other secondary particles.

The equilibrium spectra of secondary cosmic-ray positrons
Journal of Physics G: Nuclear Physics, 1986The production spectra of charged hadrons ( pi +or-, kappa +or-) from the interaction of cosmic rays with the interstellar medium are first calculated based on newly parametrised inclusive cross sections of hadrons, taking exact kinematic limitations into account.

On the secondary production of galactic cosmic ray electrons
Astrophysics and Space Science, 1972The differential energy spectrum and charge ratio of primary cosmic ray electrons produced by collisions of primary cosmic ray particles with the interstellar medium is calculated by means of the two temperature statistical model of high-energy interactions. Two realistic models for the primary cosmic ray flux are considered.
