Abstract : A reformulation of the Blunck and Westphal theory of electron energy loss in metals was performed for the metals beryllium, aluminum, copper, tin, gadolinium, and lead. Comparison with previous theoretical calculations shows good agreement for the most probable energy loss and for the full widths at half maximum of the electron energy loss distributions. The computer program designed for these calculations is given. It is an improvement over previous programs in both computation time and simplicity. A semi-empirical formula for the most probable energy loss was calculated. This formula agrees, within a few percent, with the most probable energy loss calculated according to the Blunck and Westphal theory except in the case of thick (>3 gm/sq cm) absorbers of heacy elements. The full width at half maximum for the energy loss distribution is presented in graphical form as functions of target thickness and atomic number. (Author)
