A detailed analysis of the experimental error sources is provided. The experimental results are compared with integral elastic and inelastic cross sections calculated using the independent atom model approximation and a modified single-center additivity rule for electron energies ranging from 1 to 10,000 eV. The accuracy of these approximations method is discussed through a comparison with the experimental results. Previous cross-sectional data for SF 6 are compared with the present theoretical and experimental results. For SF 5 CF 3 , we present the first electron scattering cross-sectional data for the 100-10,000 eV energy range, as well as the first empirical determination of the molecular polarizability.

Integral elastic and inelastic cross sections have been calculated over a broad energy range (1 10000eV) with an optical potential method assuming an independent atom representation. Dipole rotational excitations have also been included in the framework of the first Born approximation. From a detailed evaluation of the present results and their comparison with previous theoretical and experimental data, a set of recommended integral cross sectional data is provided. By combining these data with an average excitation energy derived from the experimental energy loss spectra, the stopping power of electrons in H2O has been obtained from 5 to 5000eV .

A partir de cartes équilibrées, nous proposons un modèle cinématique de cette partie frontale des Andes. La carte équilibrée finale montre que la structuration du Coude de Santa Cruz implique le développement de décrochements, sénestres dans sa partie nord, et dextres dans sa partie sud. Ces mouvements transversaux, pratiquement nuls au front de la chaîne, s'intensifient progressivement vers la Cordillère oh ils peuvent atteindre plusieurs dizaines de kilomètres. Kinematic model of the Subandean Zone of the Santa Cruz Bend (between 16"s and 19"S, Bolivia) deduced from map balancing Abstract -Between 16's and 19'S, die Sirbaiidean Zone is characterized by lateral variations iti structural geonietiy and sliorteiiiiig directions. The constri(cfio)i of balanced maps leads to a suggested kinenlatic niodel of this fiontal part of the chain. The $na1 balanced map shows that the structuratioii of the Sanra Cruz Berid iin~ohes strike-slip niotions, sinistral in the north and dextral iiz the south. The intensity of these lateral displacements increases from the foreland to the Cordillera, where they can reach several tens of kilometres.

For the production aspects we discuss π 0 and η production in nucleon-nucleon collisions and the behaviour of hadrons in various sum rules. For the decays we present a discussion on various K, η and π decay channels. Other aspects discussed are a new treatment of meson-meson scattering, the light-by-light contribution to the muon anomalous magnetic moment and progress in various aspects of the p 6 generating functional in the mesonic sector.
