Energy loss distributions of electrons with initial kinetic energies of 1.52, 2.65 and 3.66 MeV were measured after penetration through Al, Cu, Ag and Au targets with thicknesses ranging from 0.2 to 0.7 g/cm2. The most probable energy lossW and the widthB of the distributions were compared with theoretical results. Fair agreement is obtained forW if the pathlength distribution due to multiple scattering of the electrons in the target is taken into account. This pathlength distribution was obtained by a slight modification ofYang's formula. ForB a discrepancy remained especially for the highZ materials which is probably due to an underestimation of the bremsstrahlungbroadening in the theory ofBlunck andWestphal for energy loss distributions.
