Unravelling Tungsten atom ionization at high energies: A relativistic electron impact study

The high-energy electron impact ionization of atoms is a significant phenomenon in understanding atomic behaviour, and it can provide valuable information related to electron-atom scattering. In the case of the nuclear fusion process, electron and atom scattering done at high energy can provide precious information. In the present study, we report triple differential cross-sections (TDCS) and spin asymmetry for tungsten atoms’ electron impact K shell ionization at relativistic energies regime. The relativistic distorted wave Born approximation (rDWBA) formalism has been used with the coplanar asymmetric geometrical arrangement to calculate TDCS and spin asymmetry. The TDCS and spin asymmetry have been calculated for the high incident energy from 250 keV to 700 keV, for various scattering angles $2^o$, $5^o$, $8^o$ and $14^o$ to create consistent with findings of (e, 2e) experiments of Schule and Nakel.
