In order to estimate the influence of surrounding helium on the van der Waals interaction between heliophilic and heliophobic dopants that could be investigated in our lab with ESR spectroscopy, we apply density-functional theory to simulate a double-dotation of He-clusters with Rb and Xe atoms. Simulations of a double-doped He$_{N}$ droplet with N\,=\,500 show that the alkali metal atom stays on the surface, whereas the Xe atom sits in the middle of the droplet. The van der Waals attraction between Rb and Xe is not strong enough to compensate the separation of the heliophilic Xe and the heliophobic Rb caused by the helium droplet: a potential barrier of 23.4\,K has to be overcome, which is to be compared with the 0.4 K internal temperature of the droplet. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title Xe AND Rb ATOMS ON HELIUM NANODROPLETS: IS THE VAN DER WAALS ATTRACTION STRONG ENOUGH TO FORM A MOLECULE? en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
