K-Shell Photoelectric Cross Sections from 200 keV to 2 MeV

The Spectrum of GRB 930131 ( “ Superbowl Burst ” ) from 20 keV to 200 MeV

We have constructed a broad-band spectrum for GRB 930131 (the “Superbowl Burst”), ranging from 20 keV to 200 MeV, by combining spectral information from the Gamma Ray Observatory’s BATSE, COMPTEL and EGRET instruments. We present general methods for combining spectra from different time intervals obtained by the same instrument as well as for combining spectra from the same time interval taken ...

Measurements of K-shell ionization cross sections of Cr, Ni and Cu by impact of 6.5–40 keV electrons

Results from measurements of K-shell ionization cross sections of the elements Cr, Ni and Cu by electron impact with energies in the range 6.5–40 keV are presented. Cross sections were obtained by measuring characteristic x-rays emitted from (1–6 nm thick) films of the studied elements deposited on self-supporting carbon backing films. The procedure yields relative cross sections with uncertain...

Copper K-Shell Emission Cross Sections for Laser–Solid Experiments

LLE Review, Volume 135 173 Introduction Fast-electron generation in laser–plasma interactions has long been of interest for a variety of reasons, such as avoiding preheat during compression in inertial confinement fusion (ICF), heating the compressed core of an ICF target for fast ignition,1 generating a shock in an ICF target for shock ignition,2 and as a means to produce energetic secondary p...

K-shell, L-shell and M-shell Ionization Cross Sections of Uranium Atom by Electron Impacts

The theoretical model, developed by Khare model, has been modified to calculate the total cross sections for K-shell, L-shell and M-shell ionization of uranium (Z=92) atom due to electron impact at incident electron energy from ionization threshold to 1 GeV. The various calculated cross sections are in remarkable agreement with available experimental data and other theoretical cross sections. P...
