This book was released on 1994 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE THESE PRESENTE L'ETUDE DE DEUX SCHEMAS DE POMPAGE D'UN LASER X-UV EMETTANT DANS LA REGION DE 200 ANGSTROMS. POUR LE SCHEMA DE POMPAGE PAR RECOMBINAISON NOUS AVONS ETUDIE L'INCIDENCE DES SURINTENSITES PRESENTES LE LONG DE LA LIGNE FOCALE SUR LE FACTEUR DE GAIN DES TRANSITIONS 3-4 ET 3-5 D'IONS LITHIUMOIDES ET NOUS AVONS MONTRE EXPERIMENTALEMENT QU'ELLES REDUISENT LA DUREE D'AMPLIFICATION. NOUS AVONS MONTRE QUE L'UTILISATION D'OPTIQUES LISSANTES, REALISEES A L'AIDE DE MATRICES DE LENTILLES, AUGMENTE AU CONTRAIRE CETTE DUREE. L'ETUDE NUMERIQUE ET EXPERIMENTALE DE LA TRANSITION 4F-5G (206,5 ANGSTROMS) DANS LE SOUFRE LITHIUMOIDE A MONTRE D'AUTRE PART QUE LE FACTEUR DE GAIN DE CETTE RAIE EST PEU PERTURBE PAR LES SURINTENSITES DU LASER INCIDENT. POUR LE SCHEMA COLLISIONNEL, NOUS AVONS MONTRE QUE LA TRANSITION 2P#53P J=O -> 2P#53S J=1 DU ZINC NEONOIDE PRODUIT UN COEFFICIENT DE GAIN (5 PAR CENTIMETRE) PLUS GRAND QUE LES TRANSITIONS J=2-> J=1 (2,5 PAR CENTIMETRE). CE RESULTAT PREVU PAR LES SIMULATIONS NUMERIQUES, N'AVAIT JAMAIS ETE OBSERVE EXPERIMENTALEMENT. L'AMPLIFICATION DU RAYONNEMENT A 212 ANGSTROMS (J=0->1) EN DOUBLE PASSAGE A PERMIS D'OBTENIR UN FACTEUR DE GAIN 17 AVEC UNE INTENSITE D'EMISSION QUASISATUREE. UNE MESURE DE LA BRILLANCE (PAR IMPULSION) DU LASER X A 212 ANGSTROMS (10#1#3 PHOTONS PAR MILLIMETRE CARRE PAR MILLIRADIAN CARRE) MONTRE QU'IL SE PLACE AU PREMIER RANG DES SOURCES X-UV EXISTANTES. CES RESULTATS SONT OBTENUS AVEC LE LASER DU LULI A PALAISEAU DONT L'ENERGIE DE POMPAGE EST PLUSIEURS FOIS PLUS FAIBLE QUE CELLE REQUISE DANS DES EXPERIENCES SEMBLABLES MENEES AILLEURS

Download or read book Basic Concepts for Simple and Complex Liquids written by Jean-Louis Barrat and published by Cambridge University Press. This book was released on 2003-03-27 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting a unified approach, this book focusses on the concepts and theoretical methods that are necessary for an understanding of the physics and chemistry of the fluid state. The authors do not attempt to cover the whole field in an encyclopedic manner. Instead, important ideas are presented in a concise and rigorous style, and illustrated with examples from both simple molecular liquids and more complex soft condensed matter systems such as polymers, colloids, and liquid crystals.

Download or read book Integrative Biophysics written by Fritz-Albert Popp and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the specialists working in this interdisciplinary field of physics, biology, biophysics and medicine are associated with "The International Institute of Biophysics" (IIB), in Neuss, Germany, where basic research and possibilities for applications are coordinated. The growth in this field is indicated by the increase in financial support, interest from the scientific community and frequency of publications. Audience: The scientists of IIB have presented the most essential background and applications of biophotonics in these lecture notes in biophysics, based on the summer school lectures by this group. This book is devoted to questions of elementary biophysics, as well as current developments and applications. It will be of interest to graduate and postgraduate students, life scientists, and the responsible officials of industries and governments looking for non-invasive methods of investigating biological tissues.

Download or read book Diffusion in Materials DIMAT 2011 written by Igor Bezverkhyy and published by Trans Tech Publications Ltd. This book was released on 2012-04-12 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Conference on Diffusion in Materials (DIMAT) is the benchmark conference series for diffusion in solids. DIMAT 2011 was organized by the University of Bourgogne in association with CNRS, Dijon (France). The conference showcased new results concerning theoretical tools as well as applied research approaches. Diffusion processes affect all types of materials: nanomaterials, materials for energy, metallurgy, glasses and ceramics, but each requires its own numerical tools. Volume is indexed by Thomson Reuters CPCI-S (WoS). This volume comprises most of the contributions presented at DIMAT 2011: 4 plenary lectures delivered by famous high-level scientists plus 88 contributions in the form of keynote lectures, talks and posters.
