Scientific paper

An attempt has been made to understand the electron-proton abundance ratio in cosmic rays observed near earth. After correction for interplanetary and interstellar effects, the ratio has been obtained near the 'source' boundary. A leaky source model which can describe consistently all components of the cosmic radiation was then used to obtain the abundance inside the 'source'. Possible effects of injection and acceleration processes on the ratio are examined. From these considerations the most plausible mechanism seems to be injection of electrons and protons by hot gas, their acceleration by a combination of Fermi and betatron processes, and subsequent leakage of particles into interstellar space in a rigidity-dependent fashion.
