摘要: New experimental and theoretical cross-section data for inelastic collision processes of Li atoms in the ground state excited states (up to n = 4) with electrons, protons, multiply charged ions have been reported since database assembled by Wutte et al. [Atomic Data Nuclear Tables65, 155, 1997] was published. These new were included a process critical assessment led creation modeling energetic lithium beams probing fusion edge plasmas. The electron-impact part present covers excitation ionization, having extended advanced close-coupling calculations which provide standard quality especially transitions between states. heavy-particle impact include electron removal (the sum ionization capture). Hitherto, ion-impact cross sections (except main Li(2s → 2p) process) based on scaling relations using corresponding sections. We now performed large-scale atomic orbital large number as well measurements toward development database. recommended considered fitted simple analytic expressions. analytic-fit expressions tables parameters entering these fits are here presented. also graphical form together underlying section if available.
