| 英文摘要 | Plasma screening effects on the high-energy electron-impact excitation of hydrogenlike ions are investigated under the first born approximation. the screening interactions are described by the debye-huckel model, and the wave functions are calculated numerically in a symplectic scheme. the generalized oscillator strengths (gos) for transitions between the principal quantum number n <= 3 bound states are presented, and as an example, the scaled differential cross sections and total cross sections for 1s -> 2s and 2p and 2s -> 2p transitions are also given. it is found that the plasma screening interactions reduce the gos for transitions between the states with different n and increase the gos between the states with same n. the differential and total cross sections are decreased as the screening interactions increase. |
