ELECTRON NUMBER DISTRIBUTION IN ELECTRON-PHOTON SHOWERS IN AIR AND ALUMINIUM ABSORBERS
Numerical results for the number distribution. average numbers, and variance of electrons above a given energy due to primary electrons and photons are presented for air and aluminum absorbers. The 276 tables cover the cases for electron and photon primary energies E/sub 0/ = 50, 100, 200, electron secondary energies E = 5, 10, 20, 50, 100, 200, ranging from zero to 10 radiation lengths. The more accurate Bethe-Heitler cross sections at low energies were used. Collision losses and Compton effect were taken into account. Scattering at low energies was neglected for the present low atomic number absorbers. The results were obtained using Monte Carlo methods on the electronic digital computer SILLIAC. In every case at least 1000 showers were followed to obtain the present numerical values. (auth)
