Description
We analyzed the energy dependence of electron stopping powers (SPs) calculated for 41 elemental solids from experimental optical data for electron energies between 100 eV and 30 keV. Our analysis was performed with the Hill equation to represent a series of steps in plots of the slopes of Fano plots. The average root-mean-square difference between SPs from fits with an equation derived from the Hill equation and the calculated SPs was 1.0%. The new equation can provide SPs over a wide energy range for Monte Carlo simulations of electron transport with the continuous slowing-down approximation.
