On Flammersfeld's Range-Energy Relation for Electrons



Flammersfeld Range-Energy relation for electrons in Aluminium has been examined. It is found that it is satisfactory for E > 0,2 Mev. For lower energies a power relation E = C Rm is suitable. dE/dR as calculated from these equations differs considerably from the theoretical results. Possible reasons for the discrepancy have been discussed.
