A new model for electron ranges in solid materials

[摘要] A new definition is proposed for the range of fast (1-50 keV) electrons in solid materials: the spherical range. Associated with a simple model it permits calculation of the transmission of electrons through foils and the escape efficiency of electron yield measurements in surface studies such as X-ray absorption fine structure. For materials of moderate to high atomic number (Z > 25) the spherical range takes better account of the effects of elastic scattering on the range than the usual extrapolated range parameter.
