Scattering of Metastable Rare-Gas Atoms
Radiation Research, 1974The nature of the interaction, as well as the reaction of a metastable rare-gas atom, with a ground-state rare-gas atom is investigated using elastic differential cross sections measured by the crossed-molecular-beam method. In a crossed-molecular-beam experiment, the initial conditions of colliding pairs, such as the relative kinetic energy of ...

JETP Letters, 2012
A rapidly developing field, experimental physics of ultracold gases of Fermi atoms, is briefly reviewed. The contribution of this field to fundamental physics is shown along with connection to other fields which explore systems of Fermi particles. The basic parameters of atomic Fermi gas are described together with its unique properties and advantages ...

WHEN the 2001 Nobel Prize for Physics was awarded to Eric Cornell and Carl Wieman from JILA in Boulder, Colorado, and to Wolfgang Ketterle from the Massachusetts Institute of Technology, they were recognized for creating and studying Bose–Einstein condensates – dilute gases of atoms that are all in the same quantum state.

Atom-atom potentials and rare-gas–graphite interactions
Physical Review B, 1989L'interaction entre gaz rares et graphite est modelisee comme une somme d'interactions des paires d'atomes, en utilisant le potentiel exact d'interaction non liante 3 Σ u + entre les paires d'atomes d'hydrogene et le potentiel HFD-C d'Aziz pour l'interaction du xenon et de l'argon.

Gas-phase atomization in analytical atomic spectrometry
Fresenius' Zeitschrift für analytische Chemie, 1989The most important problems of analytical atomic spectrometry are introduction of the sample into the atomizer and atomization of the sample. To solve these problems gas-phase atomization is suggested. This consists of preliminary isolation of the elements to be determined in the form of gaseous (volatile) compounds with subsequent gas-chromatographic ...

Primary Atomization in an Airblast Gas Turbine Atomizer
2012This study focuses on the spray atomization, transport and impact on a solid substrate under cross-flow conditions, as used in airblast atomizers with prefilmers for aero engines and gas turbines. The phenomena are observed using a high-speed video system and the spray is characterized using the phase Doppler technique. The governing mechanisms of drop

A dense gas of laser-cooled atoms for hybrid atom–ion trapping
Applied Physics B, 2017We describe the realization of a dark spontaneous-force trap of rubidium atoms. The atoms are loaded from a beam provided by a two-dimensional magneto-optical trap yielding a capture efficiency of 75%. The dense and cold atomic sample is characterized by saturated absorption imaging.

The purpose of this work was to test the applicability of atomization to absorption by means of a two-fluid or gas-atomization nozzle. Since absorption depends directly on the amount of liquid surface exposed to absorbable gas, and atomization of a liquid produces the largest possible surface to mass ratio, it was felt that absorption by this method ...
