In their simulations the inelastic electron-scattering probability is proportional to Im[1/e(q, co)], where A'q and fico are the momentum and energy transfers, respectively.…”

Various experimental methods based on positron annihilation have evolved into important tools for researching the structure and properties of condensed matter. In particular, positron techniques are useful for the investigation of defects in solids and for the investigation of solid surfaces. Experimental methods need a comprehensive theory for a deep, quantitative understanding of the results. In the case of positron annihilation, the relevant theory includes models needed to describe the positron states as well as the different interaction processes in matter. In this review the present status of the theory of positrons in solids and on solid surfaces is given. The review consists of three main parts describing (a) the interaction processes, {b) the theory and methods for calculating positron states, and {c)selected recent results of positron studies of condensed matter.

“…The knowledge of the collision processes can be encapsulated in scattering cross-sections generally used either to simulate electron trajectories via Monte Carlo (MC) simulations [6][7][8][9][10] or to provide stopping powers and transport cross-sections needed for analytic transport theory [11,12]. In fact, the transport cross-section is a quantity of prime importance.…”

A Monte Carlo (MC) strategy that combines the effective differential cross section for elastic scattering of electrons and the continuous slowing-down approximation for the description of inelastic energy loss is proposed. Depth-dose distributions, backscattering and transmission coefficients are simulated using this MC strategy for electrons with primary energies 10 keV E 1 MeV passing through the Al target. The results of these simulations are in good agreement both with the results obtained from the detailed MC simulation and with experiment. The proposed MC strategy significantly decreases the total number of collisions experienced by electrons in matter and hence significantly decreases the computational cost in the MC simulation.
