When electronically excited CO(a(3)Π) collides with a Au(111) surface, electron emission can be observed with a quantum efficiency of 0.13. We have studied the influence of Ar, Kr and Xe adsorption on the electron emission efficiency resulting from CO(a(3)Π) quenching. Surprisingly, a single monolayer (ML) of rare gas dramatically enhances electron emission. For Ar and Kr bilayers, emission eff...

Abstract Recent reviews of the hyperfine structure xenon and krypton have highlighted variety values taken by coefficients A B these atoms. These variations, as functions atomic angular momenta, were however not explained quantitatively. This article shows simple picture momentum algebra that make it possible to account for observed trend. The only necessary approximations are consider interaction...

Mercury lamps are typically the major light sources in water treatments. However, use of mercury has raised some concerns with regard to Minamata Convention on Mercury. As such, Hg-free microwave discharged electrodeless (MDELs) that incorporate a rare gas and halogen (R/H-MDEL) have been investigated such mixture filler gases as Kr/Cl2, Xe/Cl2, Kr/Br2 (R/H). Of these, only Kr/Br2-MDEL lamp is ...

The accuracy and transferability of the electronic structure approach combining dispersionless density functional theory (DFT) [K. Pernal et al., Phys. Rev. Lett. 103, 263201 (2009)] with the method of increments [H. Stoll, J. Chem. Phys. 97, 8449 (1992)], are validated for the interaction between the noble-gas Ne, Ar, Kr, and Xe atoms and coronene/graphene/graphite surfaces. This approach uses...
