Change in Cosmic-Ray Spectrum Through the Production of Electron–Positron Pairs (Analytical Approach)

摘要

We consider the change in primordial cosmicray spectrum through the production of electron– positron pairs in collisions with cosmic microwave background radiation photons. We suggest using these results to estimate the distances to cosmicray sources.We consider the change in primordial cosmicray spectrum through the production of electron– positron pairs in collisions with cosmic microwave background radiation photons.
