Electron scattering from molecular targets using relativistic model-potential framework

Electron–molecule scattering plays a central role in electron-driven processes across semiconductor technology, astrophysical environments, and radiation-damage physics, where reliable cross sections are required over a wide energy range. In this work, I will present a relativistic framework for electron scattering from molecular targets that can be applied consistently from low to high incident energies and is sensitive to the basic features of molecular structure. The approach is based on the Dirac partial-wave formalism combined with a spherical complex optical-model potential, with molecular potentials built using a group-additivity scheme. By solving the coupled radial Dirac equations, we obtain phase shifts that are used to generate differential, elastic, inelastic, momentum-transfer, and total cross sections. The framework naturally incorporates geometry-dependent effects through the construction of the molecular potential, providing a consistent route to high-quality scattering data for modeling electron-induced phenomena in diverse physical and technological fields.
