An ‘‘optical‐data’’ model for describing the dielectric response function of a medium was introduced earlier to predict energy‐loss rate and inelastic mean free path for low‐energy (

These lectures cover special topics about the interaction of swift electrons with condensed matter. The focus is on inelastic processes via the linear response function of the medium and sum rules that it satisfies. The spin dependence of low-energy

The optical properties of thin films of poly(butene‐1‐sulfone), PBS, an electron beam resist, are presented for the range of photon energies from 2.5 to 39.0 eV. The density of these films is found to be (1.39 ± 0.02) g cm−3. A sum‐rule calc

Theoretical models and calculations are combined with experimental optical data to determine a model energy-loss function for SiO2. Sum-rule checks and comparisons with experimental information are made to insure overall consistency of the model. The

Energy-loss straggling of ions with v\ensuremath{\ll}${v}_{F}$ in an electron gas has been evaluated from phase shifts determined from nonlinear, density-functional calculations. These results differ markedly from those obtained from linear theory an

The continuous-slowing-down-approximation range and range straggling for electrons with energies ? 10 keV in Al, Au, Ag, and Cu are calculated. The mean energy loss per unit pathlength, or the stopping power, is described by a statistical electron ga

The cross section for X-ray excitation of surface plasmons on a spherical void in an electron gas is derived using a hydrodynamical approximation. The result is compared to the cross sections for elastic scattering from the void, and other inelastic
