The Mass of Cosmic Rays of Ultra High Energy

A A Watson

A review of several analyses is presented that forces the conclusion that the mass composition of the highest-energy cosmic rays is not proton-dominated. This deduction, combined w…

Further Evidence for an Increase of the Mean Mass of the Highest-Energy Cosmic-Rays with Energy

A A Watson

Sokolsky and D_Avignon have recently reported an examination of a variety of measurements that relate to the question as to how the mass composition of the highest-energy cosmic-ra…

The mass composition of cosmic rays above 10^17 eV

A. A. Watson

Our knowledge of the mass composition of cosmic rays is deficient at all energies above 10^17. Here systematic differences between different measurements are discussed and, in part…
