“…The scattering observables have applications in surface analysis technique, electron microscopy, electron-probe microanalysis, design of radiation detectors, radiation therapy and protection, astrophysics, atmospheric sciences, biological sciences, gas discharges, plasma physics, X-ray lasers, etc. [1][2][3][4] Determination of critical minima (CM) in DCSs, in the vicinity of which the maximum polarization occurs, 5) is used in testing fundamental predictions of quantum mechanics. Polarized beams of electrons are applied in the transfer of polarization from electrons to photons.…”

This work calculates the differential, integral and momentum transfer cross sections for the scattering of e ± by the neutral neon over the energy range 1 eV-0.5 GeV and those of e − by the ions (Ne + -Ne 10+ ) over the range 1 eV-1 keV. It also includes the estimation of the viscosity, inelastic, total and total ionization cross sections and Sherman function for the e ± -atom systems over the same energy range. Our calculations involve two approaches, the optical potential model (OPM) and the nuclear structure approach (NSA), depending upon the collision energy. Both the approaches employ Dirac partial wave analysis but differ in the potentials. In OPM, a complex projectile-target optical potential, comprising static, exchange, polarization and imaginary components, is employed. In the NSA, only the nuclear potential is used, neglecting the screening of the electrons. Moreover, we have determined positions of critical minima, in energy and angle, from the analysis of elastic differential cross sections and Sherman function at different energies. Our results agree reasonably well with the available experimental data and other theoretical calculations.

“…Theory of the elastic scattering of electrons and positrons from positive ions provides some simple testing grounds of atomic structure and collision dynamics. Moreover this theory carries enormous importance for the spectroscopic clarifications and theoretical modeling of the formation and time evolution of artificial, terrestrial, space and astrophysical plasmas [1]. Data of electron-ion collisions are required in such applied and research areas as atmospheric physics, radiation dosimetry, nuclear medicine, radiation biology, radiotherapy, fusion energy research, semiconductor lithography, x-ray lasers, etc [2][3][4].…”

This work presents the calculations of differential, integrated elastic and momentum transfer cross sections for the elastic scattering of electrons from the ions of xenon isonuclear series over the incident energy range 1 eV–1000 eV. Coulomb glory, the amplification of elastic backscattering of electrons from positive ions owing to the electrostatic screening of nuclear potential by atomic electrons, is investigated throughout the ionic series of xenon, argon and neon. Cross sections for the angular distribution of elastically scattered positron from selected xenon ions are also calculated. Energy dependency of differential cross sections and Sherman functions are predicted for both the projectiles and a comparison is presented to exhibit the dissimilarity arising out of the difference of the interactions of the projectiles with ions. The theoretical methodology of this work employs the Dirac relativistic partial wave analysis using a complex optical potential, comprising static, exchange, polarization and imaginary components, and a pure Coulomb potential. The results obtained show reasonable agreements with the available experimental data and other theoretical calculations.

“…The collision data are not only used for unraveling electron-ion interactions, but also in such applied areas as microdosimetry, radiation dosimetry, nuclear medicine, radiation therapy and protection, various electron spectroscopic technologies, etc. The electron-ion elastic scattering data are also immensely needed in understanding behaviors of plasmas occurring in solar corona, astrophysical objects, atmosphere, gas discharges, fusion plasmas, x-ray lasers, etc [1,2]. In passage through matter such as argon discharge tube, other laboratory and astrophysical plasmas, etc the electron is not only scattered, but also produces ions of different charges.…”

Absolute angular differential, integrated elastic and momentum transfer cross-sections for elastically scattered electrons from the ions ( ) of argon isonuclear series, over the energy range 3.3–100 eV, are calculated employing a complex electron-ion optical potential within the framework of Dirac relativistic partial wave analysis. The cross sections are analyzed in terms of the contributions from pure Coulomb filed and the short range electron-ion complex optical potential comprising static, exchange, correlation-polarization and absorption potentials. Comparison of our calculations with the available experimental data and other theoretical calculations shows a satisfactory agreement.
