The reactivity of laser-excited Ca+* ions in 3 2DJ (J = 3/2, 5/2) states with neutral H2O molecules was experimentally investigated. The reaction-product ions were sympathetically cooled by laser-cooled 40Ca+ ions and detected by laser-induced fluore

A long series of simulations of hairpin-filament guns as used in electron spectrometers was performed for filament-anode distances from 2 to 10 mm and acceleration voltages from 10 to 100 V using Child's law approximation, space-charge effects and ro

We show from simple conductance considerations in the intermediate flow regime, i.e. in the pressure regime adjoining molecular flow, that a nonlinear behaviour of the flow rate as a function of backing pressure behind a nozzle is to be expected. For

There remain discrepancies in the determination of the total and elastic cross sections for electron and positron collisions with carbon dioxide at impact energies from 0.3 to 100 eV. We have carried out a joint experimental and theoretical study in
