... So we need to make approximations. The outer electrons are screened by the inner electrons so the effective charge they feel is less than Ze which we can write as Zeffe. If one electron is well outside of the other Z−1 electrons it feels a charge of just 1e (i.e. Zeff = 1). This screening is basical ...

... This discrepancy implies that we are using the wrong value for L & that the scattering sites for electrons are not adjacent ion cores but more widely separated scattering centres. We can account for the unexpectedly long electron mean free path by taking the wave nature of the electron into account. ...
