Download Di-photon and Photon + B/c Production Cross Sections at Ecm Book in PDF, ePub and Kindle
Measurements of the di-photon cross section have been made in the central region and are found to be in good agreement with NLO QCD predictions. The cross section of events containing a photon and additional heavy flavor jet have also been measured, as well as the ratio of photon + b to photon + c. The statistically limited sample shows good agreement with Leading Order predictions.

Download Photon Cross-sections at ECM Book in PDF, ePub and Kindle
Photon production rates have been studied by the D0 and CDF experiments in Run II of the Fermilab Tevatron Collider. Measurements of the inclusive isolated photon cross section and the di-photon cross section are presented, based on integrated luminosities of 0.3 fb{sup -1} and 0.2 fb{sup -1}, respectively. The results are compared to perturbative QCD calculations in various approximations.

Download Low Energy Electron and Photon Cross Sections for O, N2, and O2, and Related Data Book in PDF, ePub and Kindle
The purpose of this report is to provide a set of low energy (0-300 eV) cross sections for use in calculating the photoelectron flux in the terrestrial daytime ionosphere. Also given are data on the neutral particle composition of the upper atmosphere and ionizing electromagnetic radiation from the sun.

Download Cross Sections for Electron and Photon Processes Required by Electron-transport Calculations Book in PDF, ePub and Kindle
Electron-transport calculations rely on a large collection of electron-atom and photon-atom cross-section data to represent the response characteristics of the target medium. These basic atomic-physics quantities, and certain qualities derived from them that are now commonly in use, are critically reviewed. Publications appearing after 1978 are not given consideration. Processes involving electron or photon energies less than 1 keV are ignored, while an attempt is made to exhaustively cover the remaining independent parameters and target possibilities. Cases for which data improvements can be made from existing information are identified. Ranges of parameters for which state-of-the-art data are not available are sought out, and recommendations for explicit measurements and/or calculations with presently available tools are presented. An attempt is made to identify the maturity of the atomic-physics data and to predict the possibilities for rapid changes in the quality of the data. Finally, weaknesses in the state-of-the-art atomic-physics data and in the conceptual usage of these data in the context of electron-transport theory are discussed. Brief attempts are made to weight the various aspects of these questions and to suggest possible remedies.

Download Total Photon Absorption Cross Section Measurements, Theroretical Analysis and Evaluations for Energies Above 10 MeV Book in PDF, ePub and Kindle
Atomic photoabsorption cross sections have been calculated in the energy range from 10 MeV to 350 MeV. For Pb, Ta, Sn and Cu total y-ray absorption cross sections were measured between 10 MeV and 160 MeV and compared with the theoretical results. An estimate of the uncertainties in the calculated atomic cross sections is given.
