Probing Tip with Xenon Atom to Measure van der Waals Forces (image) University of Basel Share Print E-Mail Caption Rare gas atoms deposited on molecular network are investigated with a probing tip, which is decorated with a xenon atom. The measurements give information about the weak van der Waals forces between these individual atoms. Credit University of Basel, Department of Physics Usage Restrictions Give adequate credit.
