Electron capture to nearly circular states in low energy collisions of Ar8+ with cesium

Vacuum ultraviolet spectroscopy has been used to study one electron capture into Ar8+ ions from cesium at 16, 80 and 160 keV energies. Many Δn=1 to 5 transitions have been observed. The line intensity distribution is compared to theoretical distributions. The best agreement is obtained with the three body Classical Trajectory Monte Carlo calculation of Pascale et al.
