Abstract :In dealing with electron interactions with matter, it is important to reveal the relationship between parameters such as stopping power, range and absorbed dose. It is known that the change of mean excitation energy values, which is a quantity affecting stopping power and range calculations, according to the atomic number of the elements, confirms the shell model of the elements. In this study, it was revealed that the d_max value, which is closely related to dose values, is also compatible with the shell model of the elements and exhibits similar behavior with the mean excitation energy. For this purpose, EGSnrc Monte Carlo code was used to determine the d_max values. Calculations were carried out for three electron energies (4, 9 and 15 MeV) in medically important energy ranges. As a result, the shell structure of the elements should be taken into account in the calculation of electron interaction parameters.
