In this paper we will discuss experiments performed using an accelerated ion beam incident on selected targets. Some of these were: 1) Measuring Rutherford scattering and/or non-Rutherford nature of scattering as a function of scattering angle, energy of the ion beam and atomic number 2) Verifying theoretical prediction of the kinematical scattering factor by measuring the scattered ion energy 3) Particle Induced X-ray emission (PIXE) and/or Rutherford scattering to determine the elemental thickness and test the theoretical prediction for the x-ray production cross sections. 4) Determination of the mass absorption coefficient of lead using gamma ray spectroscopy 5) Nuclear reaction studies (proton on lithium fluoride) using sodium iodide detector6) Applying X-ray fluorescenceto determine elemental composition.

This historical ethnography of Los Alamos, New Mexico is derived from over twelve years of participant observation and interview research in both the community at large and the National Laboratory (including several years as a Q-cleared employee working in security and intelligence), autoethnographic interpretation of my growing up (and subject-formation) in the town, and historical and archival research about the town (including the ancient and historical residents of the Pajarito Plateau, the Anasazis and Spanish colonists, the Manhattan Project, and post-World War II Los Alamos) and the work that is conducted there. Study of the social space of Los Alamos yields perspectives on the institutions of the scientific war state and on the effects of intense security upon a community. [ABSTRACT FROM AUTHOR]

We report on the development of a new standard for exchange of atomic, molecular and particle-surface(solid)-interaction data based on the XML schema (XSAMS). The general structure of XSAMS is discussed, and future directions of XSAMS development are outlined. [ABSTRACT FROM AUTHOR]

We report on recent efforts aimed at improving the atomic data that is used in modeling tungsten spectral emission from tokamak plasmas. Results are shown from recent Dirac R-matrix electron impact excitation calculations of W46+ and from configuration-average distorted-wave electron impact ionization calculations. Collisional-radiative calculations are performed using the new data, and the results compared with those obtained using plane-wave Born electron impact excitation data. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]

Normalized doubly-differential cross-sections and differential cross-sections for the electron impact ionization, excitation to the n = 3 and 4 levels, and elastic scattering from atomic hydrogen have been measured at incident electron energies ranging from 14.6 eV to 40 eV for scattering angles of 10° to 130°. The measurements are normalized to the accurate differential cross-section for the electron-impact excitation of the H (n=2) level. These measurements were made possible by the use of a new moveable target source which enables the collection of hydrogen energy loss spectra that are free of all backgrounds. Our measurements are in very good agreement with the results of recent theoretical models—the Convergent Close-Coupling model and the Exterior Complex Scaling model. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
