STATE-SELECTIVE CAPTURE IN COLLISIONS BETWEEN IONS AND ALKALI-METAL ATOMS

We have calculated final n, 1, m-distributions for the electron capture in Na+ + Na(28d) collisions and N5+, Ar8+ + Cs(6s) collisions using a three-body classical trajectory Monte-Carlo (CTMC) method. The collision velocity range is 0.5 less-than-or-similar-to x less-than-or-similar-to 1.7. Here, x = v(p)/v(e), where v(p) is the ion projectile velocity in the laboratory frame and v(e) is the initial orbital velocity of the electron bound to the alkali-metal core. The results are discussed along with experimental data.
