Single- and double-electron transfer from He to the Ne8+(ls(2))S-0(1) ion has been studied at 80 keV by extreme ultraviolet (EUV) spectroscopy and zero-degree electron spectroscopy. Signals originating from the stabilization after two-electron captur

Double-electron capture by Ar{sup 8+} from He is analyzed. Since the incident ion beam contains a metastable fraction of the order 5{percent}, two distinctly behaving systems are considered: (1) Ar{sup 8+}(2p{sup 6}){sup 1}S{sub 0}+He{r_arrow}Ar{sup

Cross sections for the ionization-excitation of helium following electron and H+, H2+ and H3+ ion impact have been measured for He II (np) 2P0 states with n=2-5. These measurements were performed for the velocity range from 3.8-8.5 au for electrons,

In many isoelectronic sequences, there is a metastable state just above the ground state (viz. in the He-like and Ne-like sequences). When a low energy electron transfer collision is observed, involving a metastable projectile, photon and Auger decay

An experiment to measure the dielectronic recombination of ${\mathrm{C}}^{3+}$ in a known external electric field is described. The measured value differs from results of calculations which do not include the effects of field enhancement, and is larg

The population of levels with principal quantum numbers n largely in excess of the n=3 (most populated level) in the single electron capture by O6+ from He (at 60 keV) is reported. The n=4 population involves an 'electron promotion mechanism' at smal

Photon emission in the wavelength intervals 17-24 AA and 100-200 AA following single and double electron capture in collisions of O6++H2 at 3.8 keV amu-1 has been analysed. The overall single electron capture features on both ion cores are similar an

Single and double electron transfer from He into the ground state ion O6+(1s2)1S0 and the metastable ion O6+(1s2s)3S1 have been studied in collisions at v=0.39 v0. The single capture takes place dominantly into the n=3 shell for both ions; for O6+(1s
