DEPENDENCE OF LAMBDA(E) ON ENERGY

A number of expressions are suggested to approximate the dependence of electron mean free pass in the solid body on electron energy relative to inelastic collisions. They all describe quite nicely the growth of mean free path with energy increase, but have poor precision in the region of E < 100 eV. A calculator of electron mean free path in simple substances is built into the Handbook's software application (menu item PeriodicTable->Constants). Physical Constants Window and Effective analysis depth.
