Electron Momentum-Transfer Cross Section in Cesium

Abstract
An analysis of electron drift-velocity data in cesium has been conducted in order to determine the electron momentum-transfer cross section. Numerical evaluation of the drift-velocity integral using numerous trial functions for the cross section has revealed the qualitative and semiquantitative nature of the electron momentum-transfer cross section in cesium. The cesium cross section found to be most consistent with the available experimental data exhibits considerable variation with electron energy in the range 0.1-1.0 eV, the region of primary importance in plasma applications.
