Z/A dependence of the cosmic muon-electron collision cross section

A study has been made on the dependence of muon-electron collision cross section on Z/A of the target material at different muon energy, on the basis of the experimental results along with the results of Stoker et al and Das. These results show an appreciable dependence of muon-electron collision cross section on Z/A of the target material. This fact is supported by the Bhabha theory for electron energy transfer 60-160 MeV. (author)
