Doubly differential cross sections for K-shell ionization by electron and positron impact

Doubly 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 ...

K-shell ionization of atoms by electron and positron 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...

Measurements of absolute cross sections for K-shell ionization of Fe and Mn by electron impact

K-shell ionization cross sections of iron and manganese have been measured for incident electrons with energies varying in the interval from 6.5 to 40 keV, in 1 keV steps. Cross sections were obtained by measuring characteristic x-rays emitted from thin films of the elements studied deposited on carbon self-supporting backing films. Relative cross sections were obtained with uncertainties∼3%. T...

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...
