We have measured the total cross sections for single charge exchange in He2+-He+, Ne2+-Ne+ and Ar2+-Ar+ collisions at centre-of-mass energies of 1.8-14.8, 1.8-10.8 and 2.8-7.3 keV, respectively, using an intersecting beam technique. The results for H

Contributions of the electron-electron and electron-nucleus interactions to the ionization of O{sup 7+} by He are experimentally separated using recoil momentum spectroscopy. The electron-electron contribution is found to produce much smaller recoil

Beats arising from the Stark mixing of neighbouring levels in highly excited hydrogen-like carbon have been observed. Unlike previous experiments, a Rydberg analyser was used to limit the range of quantum numbers detected in the region following the

Recoil ion momentum spectroscopy is used to study the impact-parameter dependence of the single-ionization, double-ionization, single-capture and transfer-ionization channels in fast collisions of highly charged ions with He. The possibility of obtai

The recoil longitudinal momentum and {ital Q} value for electron capture with and without accompanying target ionization were measured for high-energy O{sup 7+}-F{sup 8+}+He collisions using coincident recoil momentum spectroscopy. Electron capture i

The projectile energy loss for 7.5--25-MeV C[sup 6+,5+] and F[sup 6+] ions was measured for single collisions with He, Ne, Ar, and Kr as a function of the recoil-ion charge state and the projectile scattering. This energy loss was measured for collis

Electron capture by O[sup 7,8+] and N[sup 7+] in collisions with He at 0.2--1.7 a.u. was investigated using coincident recoil momentum spectroscopy. The [ital Q] values and angular differential cross sections for single capture, transfer ionization (

Recoil momentum spectroscopy has been used to distinguish experimentally between contributions to the ionization of hydrogenlike O and F projectiles from interactions with the electrons and with the nucleus of a target He atom. The electron-electron

We report investigations of one- and two-electron processes in the collisions of 0.9-keV/u to 60-keV/u ([ital v][sub [ital p]]=0.19--1.55 a.u.) Ar[sup 16+] ions with He targets. The cross sections for these processes were measured by observing the fi

Coincidences between two sulfur {ital K} x rays were detected from collisions of hydrogenlike S ions with H{sub 2} gas in the projectile energy range between 150 and 225 MeV. These {ital K} x rays are emitted in the decay of doubly excited states for
