Double-charge-transfer (DCT) collisions of H + , OH + and F + 3 keV beam ions with a series of alkyl isocyanate molecules were studied using mass spectrometric techniques. Measurement of the kinetic energies of H − ions so produced enabled the dete

The results of a combined experimental and theoretical study of the double ionization of sulphur hexafluoride are reported. Double-charge-transfer (DCT) spectroscopy was used in the experimental investigation. Double-electron-capture (DEC) reactions,

Vertical double-ionization energies, for transitions from the ground state of the neutral sulphur dioxide molecule to both singlet and triplet energetically low-lying electronic states of the SO 2 2+ dication, have been studied both experimentally wi

It has been proposed that the endoergicities of triple-electron-capture (TEC) reactions involving doubly charged ions must fall within a reaction window from 12 to 33 eV in order that the reactions have a finite probability. The upper limit has been

The newly developed technique of triple-charge-transfer spectrometry was used to measure eight distinct triple-ionization energies of CS2 in the range 54–66 eV. A semi-empirical method was used to calculate the energies, and excellent agreement was

The results of an investigation of triple-electron capture by fast-moving (6 keV translational energy) O2+ and Cl2+ ions in single collisions with xenon atoms are reported. Although the negative-ion yields were low, repeated scanning and signal avera

The average internal energies of photoexcited ions have been varied by changing the temperature of the source in which the ions are formed and photoexciting them through constant photoexcitation energies in the field-free region of a double-focusing

Using a ZAB-2F double-focusing mass spectrometer together with an argon-ion laser, the kinetic energy spectra of N 2 + photofragments from the photodissociation of N 2 O + have been measured at wavelengths 514.5, 496.5, 488.0 and 476.5 nm in the visi
