Electron energy The energy E(x) of an electron after pass- ing through material of thickness x is given by the equation E(x) = Eoe-o, where E, is the initial energy and xo is the radiation length. (a) Express, in terms of Eo, the energy of an electron after it passes through material of thickness xp. (b) Express, in terms of xo, the thickness at which the elec- tron loses 99% of its initial energy.
