Direct Excitation in Atomic Collisions: Studies of Quasi-One-Electron Systems

摘要: Publisher Summary The study of inelastic processes in binary atomic collisions has a long history. application electron spectroscopy and collision spectroscopy—that is, energy-loss analysis the particles scattered at fixed angle, together with availability large Hartree–Fock computer codes for quantum chemical calculations molecular properties led to further advances. This chapter presents an argument that isolates key parameter from which scaling mechanism may be predicted, also underlines connection between this excitation mode phenomena neighboring subfields physics. considers theoretical approaches collisional quasi-one-electron systems particular emphasis on asymmetric alkali atom (alkaline earth ion)-rare-gas collisions—that events. optimal experimental results needed assess validity various models described are mechanical amplitudes given state.
