High-resolution core and valence band photoemission as well as photoinduced Auger spectra of metallic Sn, polycrystalline SnO and SnO2 ((110) natural single-crystal cassiterite and polycrystalline) samples were measured in order to give information on loca ...
In high-resoln. NMR spectra of scalar coupled spins in isotropic phase, it is possible to convert single- into triple-quantum coherences and vice versa by irradiating simultaneously at the frequencies of 3 chem. shifts. A triple resonance condition can be ...
We describe a simple and robust method of creating an efficient large-angle adiabatic passage beamsplitter that does not require the light fields to be pulsed. We present simulations that show momentum splittings of 80 \hbar k, where more than 60% of the a ...
Ab initio calcns. have been performed on TinO2n-δ clusters, with n = 1-3 and δ = 0, 1, as well as on some of their ionized species. The geometries of the different clusters were optimized and vibrational analyses were performed at the ground-state equil. g ...
Electron transport along open field lines in the diverted scrape-off layer of a tokamak is studied numerically via a kinetic Fokker-Planck approach. The method allows calculation of the distribution function in a situation where large parallel temperature ...
Rydberg-Rydberg transitions are induced by absorption from the lowest Rydberg state of NO A 2S+ (3ss) in Ar matrixes, which is excited by an ArF laser at 193.3 nm. The depopulation of the A(v = 0) level to higher Rydberg states is probed by depletion of it ...
A systematic study of the mass spectra of particles formed in a supersonic nozzle expansion of Zn, Cd, and Hg vapors together with Na was performed. The particles discussed in this paper contain only 1 heavy atom and
We consider the transition probability for two-level quantum-mechanical systems in the adiabatic limit when the Hamiltonian is analytic. We give a general formula for the leading term of the transition probability when it is governed by N complex eigenvalu ...
The design and operation of a new vaporizing assembly used for Q-plasma sources are described in this article. The vaporizing system, consisting of two ovens and an effuser, is used to vaporize and direct atoms onto a hot ionizer plate. The hot plate, whic ...
Abstract Using Fefferman's analysis of the quantum electron-proton gas, we give a rigorous proof of ionization equilibrium in this system. Ionization equilibrium phases are obtained as low-density and low-temperature limits, letting the chemical potentialm ...
