  2. Influence of photospheric back-scatter on flare hard x-ray diagnostics.

    Alexander, Robert CalumUniversity of Glasgow2010

    … spectrum and its effect on the inferred parent electron spectrum. I present a theoretical investigation into Compton reflected HXR photons, known as the photospheric Albedo, and explore the effect of photospheric albedo on observations of global flare hard X-ray spectra for isotropic emission. I …

  3. A valence bond for several perturbations

    Lane, Dorothy CurtisVirginia Polytechnic Institute and State University1973

    … is developed for the purpose of treating the pi electron spectra of molecules related to a parent conjugated hydrocarbon molecule. A spectral perturbation reflects the change in pi electron transition energy of the parent hydrocarbon as a result of heteroatom replacement of one or more carbon …

    Huang, Wenqian RonnyMassachusetts Institute of Technology2017

    … demonstration of the first ultrafast THz-driven electron gun, a technology with the potential to deliver unprecedented electron beam quality to scientists studying matter at the ultrafast and ultrafast scale via electron diffraction or x-ray imaging. In Part 1, we discuss various advances in …

    Rohwer, Erich Gottfried1985

    … electromagnetic deexcitation process by which an electron is emitted from an atomic elec¬tron shell. This process competes with the emission of gam¬ma-rays from the nucleus- Recently a mini-orange electron spectrometer, for the recording of internal electron spectra, was designed and built at the …

  7. AUGER ELECTRON SPECTROSCOPY OF CRYOGENIC MATRIX ISOLATED METAL ATOMS AND DIRECT RECOIL SPECTROSCOPY (DRS), SIMS AND XPS STUDIES ON TITANIUM AND PIQ

    SCHMIDT, HOWARD KHANRice University1987

    Auger electron spectra of matrix-isolated metal atoms have been recorded for the first time. Differences in extra-atomic relaxation between bulk metal and argon matrix isolated atoms resulted in shifts in the energy of LMM Auger electrons, $-3.1$ eV for potassium and $-8.7$ eV for titanium. The sum …
