Pathlength distributions of low energy electrons in water

The pathlength distributions of low energy electrons (below 10 keV) in liquid water have been studied. The stragglings of the energy loss and pathlength for electrons were investigated by the use of the straggling function. From the differential and sum distributions of the straggling function, we have determined the mean, extrapolated and most probable pathlengths. Results of this work have been compared with the continuous slowing down approximation (CSDA) pathlengths and available experimental data. (orig.)
