Long-range interactions of copper and silver atoms with hydrogen, helium, and rare-gas atoms
Dispersion interactions of the ground and resonantly excited states of Cu and Ag with a number of buffer gases are determined. The valence excitation spectrum was calculated by diagonalizing a semiempirical Hamiltonian in a large-dimension single-electron basis. The core made a significant contribution to the C6 and C8 dispersion coefficients for both copper and silver. Oscillator strengths and...
متن کاملPhotoionization of helium nanodroplets doped with rare gas atoms.
Photoionization of He droplets doped with rare gas atoms (Rg=Ne, Ar, Kr, and Xe) was studied by time-of-flight mass spectrometry, utilizing synchrotron radiation from the Advanced Light Source from 10 to 30 eV. High resolution mass spectra were obtained at selected photon energies, and photoion yield curves were measured for several ion masses (or ranges of ion masses) over a wide range of phot...
متن کاملScattering of Stark-decelerated OH radicals with rare-gas atoms
We present a combined experimental and theoretical study on the rotationally inelastic scattering of OH (X 2Π3/2, J = 3/2, f) radicals with the collision partners He, Ne, Ar, Kr, Xe, and D2 as a function of the collision energy between ∼ 70 cm and 400 cm. The OH radicals are state selected and velocity tuned prior to the collision using a Stark decelerator, and field-free parity-resolved state-...
متن کامل[Burns with lighter gas].
Attention is drawn to a particularly dangerous party activity. Balloons filled with lighter gas so as to float are used for party decorations. A case of hand burn caused by accidentally lighting such a balloon with a cigarette is reported. The method is strongly advised against, it is a much better idea to use helium for such purposes.
متن کاملLong-range interaction of two metastable rare-gas atoms
Motivated by cold-collision studies of metastable rare-gas atoms @1–4# and prospects of achieving Bose-Einstein condensation in these systems @5#, we present calculations of long-range dispersion ~van der Waals! coefficients for two atoms interacting in the ns(3/2)2 atomic states (n53 for Ne, n54 for Ar, n55 for Kr, and n56 for Xe!. The metastable states have long lifetimes, 43 s for Xe @6#, de...
