A fully quantum mechanical calculation has been performed to investigate the scattering of charged particles in nonideal classical plasmas (NICPs). Interactions among the charged particles in NICP have been depicted by a pseudopotential, derived from a sequential solution of Bogolyubov's chain equations. The Schwinger variational method (SVM) has been employed in the momentum space to compute the scattering phase shifts accurately for various plasma parameters. A detailed study has been made on the dynamics of electron-electron (e-e) and electron-proton (e-p) scattering in NICP for a wide range of plasma parameters. Special attention is paid to explore the scattering dynamics at low incident energies. In particular, scattering length and zero-energy resonances have been investigated in detail. Furthermore, effects of nonideality of plasma on the total cross section and transport cross section have also been studied.A fully quantum mechanical calculation has been performed to investigate the scattering of charged particles in nonideal classical plasmas (NICPs).
