Depth profiles of charge deposition in absorbers irradiated by electrons have been computed by using the ITS Monte Carlo system version 3.0. Plane-parallel electron beams with energies from 0.1 to 100 MeV have been assumed to impinge normally on slab

The authors have studied the dependence of the electron-backscatter factor (EBF) on mean electron energy and on backscatterer atomic number by using the semiempirical depth-dose code EDMULT. A plane-parallel electron beam is assumed to be normally in

An interpolation formula is given for the quantity Φ rad / Φ that is proportional to the radiative energy-loss divided by the total energy of the incident electron. Errors caused by the formular have been checked for three sets of values of Φ rad

The use of semiempirical multilayer depth-dose code EDMULT for evaluating the absorbed- dose coefficient K was studied with a personal computer. When multiplied by the charge per unit area, the coefficient gives the adsorbed dose in the sample irradi

An empirical equation for the transmission coefficient of mono-energetic electrons normally incident on the absorber has been formulated by modifying the expression proposed by Rao. It utilizes a semiempirical equation recently developed for the extr
