The energy distributions of electrons of about 54, 75, and 92 MeV were measured before and after passing through lead absorbers of 2 thicknesses ranging from 0.706 to 2.825 gm/cm , and through copper 2 and aluminum absorbers up to 5.726 gm/cm . The electrons were accelerated by the LINAC of the Naval Postgraduate School. A measurement to determine the optimum location of the absorber indicated that the separation between the scattering foil and absorber should not exceed 6 cm, if geometric difficulties are to be avoided. The most probable energy losses agree with the theory of Blunck and Westphal for all three materials and all thicknesses. The half-widths of the distri- 2 butions agree with theory up to thicknesses of about 2 gm/cm . For greater thicknesses the experimental half-widths of copper absorbers appear to agree with theory; the experimental half-widths of aluminum are greater than theoretical predictions; and those of lead are smaller than theory predicts.
