Scattering in non-ideal classical plasmas: Scattering length and zero-energy resonances

摘要

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.
