| Abstract: | A novel Monte Carlo method of simulating low energy electron (LEE) scattering in polybasic medium is presented. The Mott cross
section is adopted to describe the elastic scattering of LEE, and a mean cross section idea is proposed instead of usual determination
of the scattering center. The Joy’s modified Bethe equation is used to calculate energy loss of LEE. The scattering processes
of LEE in bulk PMMA have been simulated. And the electron backscattering coefficients, the electron interaction range and
energy dissipation distribution of LEE in bulk PMMA have been calculated and compared with those calculated by the method
of determining scattering center. |
