Abstract

Analytical expressions which reproduce recent reliable data on low energy (0 to ∼20 eV) electron-noble gas atom elastic scattering phase shifts are presented, allowing an accurate calculation of elastic integral and differential cross sections at any chosen energy through the use of the appropriate formulae. Fittings to the integral elastic cross sections thus obtained and to inelastic and total (elastic + inelastic) cross sections are also presented within this energy range. These expressions are of interest in Boltzmann and Monte Carlo calculations of electron drift phenomena in noble gases at low values of E p and are applicable to certain types of nuclear radiation detectors.
