Theoretical study of e± scattering by the Au atom

Scattering of e ± by H-isonuclear series

“…The DCS minima, for the scattering from a many-electron atom, are also known as Ramsauer-Townsend structures [67,68] formed by the interference effects of the projectile (e − /e + ) scattering from the individual electrons of the target atom. In our previous article [5], we found twelve minima points in DCS for heavier atom gold. The study of minima is important because the degree of polarization of scattered projectiles becomes maximam at angles and energies corresponding to minima locations in DCS [69,70].…”

“…As seen in the figure, V st is the dominant contributor throughout the energy range. The effect of the other components (i.e., the exchange, the polarization, and the absorption potentials) is less noticeable in hydrogen atom than in multi-electron systems [5] because of its single-electron nature. Up to 1000 eV, the absorption potential W abs contribution remains discernible for DCS and S(θ) of positron scattering.…”

“…A basic testing ground for atomic structure and collision dynamics is provided by the theory of the scattering of electrons and positrons from atoms, ions and molecules. The scattering cross-section data have applications in materials science, plasma physics, surface science, atmospheric physics, astrophysics, detector response studies, and radiotherapy [1][2][3][4][5][6][7][8]. Electron and positron scattering from H atom and ion serve as a fundamental process for understanding the interactions between e ± and hydrogen, and the collision dynamics for the simplest projectile-atom scattering system.…”
