“…In this figure, we compare DW results obtained with three configurations and with eight configurations to Born approximation and RDW [27] results. Available theoretical results [19,28,29] are also shown in the figure, only for energies higher than 5 eV. The presented experimental data from two experiments of Boffard et al [30,31] and one of Piech et al [32] are in rather good agreement with calculations.…”

“…We present also RDW results [17] which are quite similar in the high-energy region where relativistic effects are expected. Available theoretical data from [18,19] are also included. The Q-C formula results shown in the figure use transition probability values from NIST.…”

“…Here also, results from DW and FOMBT are compared with RDW results [17]. More theoretical results [19,[22][23][24] and also experimental results [20,25] are presented. We also show Q-C values obtained following Drawin [12] and Sobelman [26].…”

Evaluated atomic data concerning the 4sand 4pconfigurations of Ar I are averaged in order to simplify their use in various cases of Ar plasma modeling and diagnostics. These data are used here to model a low-power arcjet, running with Argon at low pressure. In so doing, they are explicitly introduced in the chemical processes included in a fluid Navier-Stokes type code, allowing for evaluation of the spectroscopically measurable level populations and of the electronic temperatures. The characteristics of the model are described and the main processes are discussed in view of the results of the calculations.

“…We take advantage of the presence of argon. The OES of argon plasmas is favourable in Visible and near-IR range and the dynamics of the excitation and radiative emission of the main energy levels is well known [35,36]. The relative intensity of some reference lines can so be used to gain insight mainly in the electron plasma properties.…”

“…The relative intensity of some reference lines can so be used to gain insight mainly in the electron plasma properties. This was done for the 751 nm (emitted from the 2p 5 level, mainly populated from the ground state argon [35]), which was one of the brightest in our OES spectra. Division by pressure factors out the effect due to the initial density of argon atoms, highlighting the contribution from the plasma electron alone.…”

A novel plasma source suitable for controllable nanostructured thin film deposition processes is proposed. It exploits the separation of the process in two distinct phases. First precursor dissociation and radical formation is performed in a dense oxidizing plasma. Then nucleation and aggregation of molecular clusters occur during the expansion into vacuum of a supersonic jet. This allows a superior control of cluster size and energy in the process of film growth. Characterization of the plasma state and source performances in precursor dissociation have been investigated. The performances of this new Plasma Assisted Supersonic Jet Deposition technique were demonstrated using organic compounds of titanium to obtain TiO<sub>2</sub> thin nanostructured films

A summary is given of many important advances in the scattering of electrons from atoms, ions, and molecules up to the summer of 2008. Recently introduced experimental techniques, which lead to more efficient studies, are discussed together with a wide range of increasingly sophisticated theoretical methods. Examples of experimental and theoretical data are presented and compared where appropriate.
