[en] This workshop is one of an annual series covering penetration phenomena of charged particles in matter. This specific workshop includes electron scattering, ion and atom scattering, stopping powers, and cluster ion impacts on solids. Abstracts were prepared for individual items in the proceedings for inclusion in the data base

[en] This book gathers the abstracts of the papers and posters presented at the eighth European Conference on Atomic and Molecular Physics (ECAMP-8). The conference topics include atomic and molecular spectroscopy, the interaction and collisions between ions, atoms, molecules, electrons, positrons and photons. During the conference, a symposium on radiation damage in bio-molecules was held involving 9 contributions whose abstracts are also in this book. The 634 poster abstracts have been classified into 14 categories: 1) fundamental concepts and antimatter, 2) atomic and molecular structure and spectroscopy, 3) atomic, molecular and electronic collisions, 4) photon interactions with atoms and molecules, 5) cold atoms and molecules, BEC and Fermi gases, atom optics, 6) quantum information, 7) clusters and nano-particles, 8) interactions with surfaces, 9) ultra-fast lasers, 10) synchrotron radiation, 11) ion recombination, traps and storage rings, 12) applications in astrophysics, 13) applications in biophysics, and 14) applications to the environment

[en] Topics covered in this conference included collisions involving photons, collisions involving electrons and positrons, and collisions involving heavy projectiles

It is distributed free of charge by the IAEA to assist in the development of fusion research and technology. In part 1, the Atomic and Molecular Data Information System (AMDIS) is presented. In Part 2, the indexed papers are listed separately for structure and spectra, atomic and molecular collisions and surface interactions. Part 3 contains all the bibliographic data for both the indexed and non-indexed references. Finally, the Author Index (part 4) refers to the bibliographic references contained in part 3

[en] Many natural phenomena can only be properly understood if one has a detailed knowledge of interactions involving atoms, molecules, ions, electrons or photons. In the laboratory these processes are often studied by preparing beams of two types of particle and observing the reactions which occur when the beams intersect. Some of the more interesting of these crossed beam experiments and their results are discussed. Proposals to extend colliding beam techniques to high energy particle physics are also outlined.

[en] This annotated bibliography includes papers on atomic and molecular processes published during 1983. Sources include scientific journals, conference proceedings, and books. Each entry is designated by one or more of the 114 categories of atomic and molecular processes used by the Controlled Fusion Atomic Data Center, Oak Ridge National Laboratory to classify data. Also indicated is whether the work was experimental or theoretical, what energy range was covered, what reactants were investigated, and the country of origin of the first author. Following the bibliographical listing, the entries are indexed according to the categories and according to reactants within each subcategory

[en] In this work, we present a formulation called the C-Functional to study collisions of low-energy positron by molecules. This formalism is based on the Schwinger Multichannel Method for positrons which although being a quite general method (it is applicable to polyatomic molecules and include polarization and multichannel coupling) is limited to the use of trial wavefunctions consisting only of square integrable basis functions (Gaussian Cartesian Function). In principle this is not a problem, considering that the Schwinger type of methods require a good description of the scattering wavefunction only in the region where the potential is non-zero. However, there exist some situations (long range potentials) where the SMC has consequences. The C-functional (CF) consists in writing the wavefunctions as a sum of a plane-wave plus a combination of trial functions (where the combination is variationally determined). The basic difference between the 2 cases (SMC and CF) is the presence in the CF amplitude of the First (FBA) and Second Born terms. Aiming the preservation of important features of the SMG, we have developed general codes (applicable to polyatomic targets) to evaluate these terms. To illustrate the CF method we show elastic cross sections ti He and H₂. (author)

[en] We report elastic integral and differential cross sections for scattering of low-energy electrons by three groups of molecular targets. Two of them are composed by the hydrides of elements in the same column of the Periodic Table and includes X H₄ (X=C, Si, Ge, Sn, Pb) and X H₃ (X=P, As, Sb). The last is formed by hydrides in the same row and includes Sn H₄, Sb H₃, Te H₂ and H I. The calculations employed the Schwinger multichannel method with norm-conserving pseudopotentials. This work aims to find similarities and differences in the cross sections in these two groups. (author). 12 refs., 4 figs
