| Abstract: | Neutral argon atom beams of 15 keV energy have been used to sputter alkali halides and the ejected positive ions have been analysed in energy, mass and angular distribution. The use of a neutral beam, rather than an ion beam, minimizes surface charge and the deflection of ejected ions by electrostatic interaction with a charged incident beam. A cluster component of the form K2Cl+, K3Cl+ 2 and higher members of the series is found for all alkali halides studied. |
