Current status of calculations and measurements of ion stopping power in ICF plasmas
More precise stopping power models for use in ICF target design need to be developed. The light ion beam ICF program is now moving into a phase where ad hoc scaling of certain key physics parameters in the stopping power models is no longer sufficient. Our goal is to predict ion ranges in ICF targets to within about 10 to 20%. A verified stopping power model is also essential in diagnosing target irradiation intensities; such data can only be inferred by target response. Presently, our area of primary concern involves calculating the stopping power of the bound electrons of partiallymore » 
Kinetic approach to stopping power calculations
The kinetic approach to stopping power calculations is explored within the framework of the binary encounter approximation by comparing two different stopping power definitions which take into account the kinetic motion of target particles. The definitions are {sigma}{sub max} {l_angle}{Delta}E{r_angle} and {sigma}{sub max} {l_angle}(u/v{sub 1}) {Delta}E{r_angle} where {sigma}{sub max}, is the crosssectional area for nonadiabatic encounters, {Delta}E is the energy lost by the projectile per encounter, u is the relative projectile/targetparticle speed, and v{sub 1} is the speed of the projectile. The average is taken over the velocity distribution of the target particles and over the encounter cross section. Amore »

Electron interaction cross sections in Al and Al$sub 2$O$sub 3$ calculations of mean free paths, stopping powers, and electron slowingdown spectra
The prospects for obtaining better theoretical calculations of experimentally interesting electron interaction effects, over a wide range of electron energies, are now considerably improved through the development of models for valence electron excitation in simple insulators and through the availability of theoretical atomic generalized oscillator strengths for inner shell electron excitation in several lowZ atomic systems. The way in which this information may be used to calculate mean free paths, stopping powers, and electron slowingdown spectra in Al metal and the insulator Al$sub 2$O$sub 3$ is briefly described.
