Debye-Huckel and ion-sphere plasma screening models have been used in a study of inelastic scattering of electrons by one-electron ions in dense, high-temperature plasmas. Cross sections for transitions among the 1s, 2s, and 2p states were calculated using close-coupling and distorted-wave descriptions. The optically allowed 1s-2p and 2s-2p cross sections are substantially reduced at all energies by plasma screening of the long-range dipole coupling. The 1s-2s cross section is less sensitive to plasma effects. For an ion of nuclear charge Z, the scaled inelastic cross sections (Z to the 4th) Q are roughly independent of Z for fixed values of E/(Z squared) and Z-Lambda or ZR-sub-z, where E is the electron's kinetic energy, Lambda is the Debye length, and R-sub-z is the ion-sphere radius.
