K-shell, L-shell and M-shell Ionization Cross Sections of Uranium Atom by Electron Impacts
نویسندگان
چکیده
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. PACS No: 34.80Dp Key word: Atomic Ionization, Electron Impact.

Ionization of K-shell electrons by electron or positron impact
The single ionization of inner-shell electrons by electron or positron impact are the fundamental processes, which still attract considerable interest in collision theory, experimental studies, and various applications. To predict the ionization cross sections, one usually employs either sophisticated numerical approaches or empirical and semiempirical formulas. Significant efforts have been al...
متن کاملMeasurements of absolute K-shell ionization cross sections and L-shell x-ray production cross sections of Ge by electron impact
Results from measurements of absolute K-shell ionization cross sections and La x-ray production cross sections of Ge by impact of electrons with kinetic energies ranging from the ionization threshold up to 40 keV are presented. The cross sections were obtained by measuring Ka and La x-ray intensities emitted from ultrathin Ge films deposited onto self-supporting carbon backing films. Recorded x...
متن کاملDoubly differential cross sections for K-shell ionization by e± impact∗
The single ionization of inner-shell bound electrons by lepton impact is a fundamental atomic process of particular interest. Recently, essential progress has been achieved in fragmentation experiments due to developments in many-particle imaging techniques, so-called reaction microscopes [1]. The measurements of the multiply differential cross sections become now feasible. We have deduced the ...
متن کاملStrong double K–K transfer channel in near symmetric collision of Si + Ar at intermediate velocity range
We present a combined study of single and double K–K electron transfer cross sections along with the single and double K-shell ionization of Ar induced by Si projectiles in the energy range 0.9–4.0 MeV u−1. The charge-state dependence of the normal and hypersatellite x-rays was used to derive the cross sections for the oneand two-electron processes, respectively. The enhancement in the fluoresc...
متن کاملThe cross sections for K-shell ionization by charged particle impact
The single ionization of inner-shell electrons by the impact of charged particles is one of the fundamental processes, which is being persistently investigated during last decades. In recent works [1-3], we have deduced the universal scaling laws for differential and total cross sections of the single K-shell ionization by electron and positron impact within the entire non-relativistic energy d...
