Electron scattering from polar hydrides using relativistic optical potential method
We extend the relativistic spherical complex optical-potential method with group additivity developed in our recent work [S. Arya and B. Antony, \textit{RSC Adv.} \textbf{16}, 13548--13558 (2026)] to molecules with permanent dipole moments. The short-range electronic collision is described by a central Dirac partial-wa...
