Triply-differential cross section for K-shell ionisation of silver by relativistic electron impact

Theoretical analysis of the relativistic first order Born approximation for inner shell (e, 2e) processes

“…For a number of years, substantial discrepancies existed between the absolute experimental data for triple differential cross sections (TDCS) for electron impact ionization of inner shells of high-Z atoms obtained by Nakel and collaborators [1][2][3][4][5] and the results of theoretical calculations of these processes [4,[6][7][8][9][10][11][12]. However recently, definite progress towards quantitative agreement between theory and experiment could be achieved with the implementation of a fully relativistic distorted wave Born approximation (rDWBA) [13][14][15].…”

Relativistic (e, 2e) collisions on atomic inner shells in symmetric geometry

“…For recent reviews see [3,4,5]. Work in the relativistic region began with the (e, 2e) experiments of Schfile and Nakel [6] and of Ruoff and Nakel [7] at an incident electron energy of 500 keV. There it was possible to measure the absolute triple differential cross section for K-shell ionisation of atoms with higher atomic numbers (Z = 47 and 73) using an energy-sharing method.…”

Energy Spectrum of Ejected Electrons of H(2P) Ionization by Electrons in Coplanar Asymmetric Geometry

“…Schüle and Nakel [19] presented experimental investigation of the energy spectrum of ejected electrons for ionization of medium-heavy atoms by relativistic electrons. However, Das and Dhar [20] have investigated energy spectrum of ejected electrons for hydrogenic ground state ionization by electrons in the non-relativistic energy region.…”
