✦ Synopsis
An exact analytical expression for the energy-averaged electron-ion momentum transport cross section in the Born approximation and Debye-Huckel exponentially screened potential has been derived and compared with the formulae given by other authors. A quantitative comparison between cut-off theory and quantum mechanical perturbation theory has been presented. Based on results from the Born approximation and Spitzer's formula, a new approximate formula for the quantum Coulomb logarithm has been derived and shown to be more accurate than previous expressions.
