Abstract

The influence of Dupree diffusivity on the occurrence scattering time advance for the electron-ion collision is investigated in turbulent plasmas. The second-order eikonal method and the effective Dupree potential term associated with the plasma turbulence are employed to obtain the occurrence scattering time as a function of the diffusion coefficient, impact parameter, collision energy, thermal energy, and Debye length. The result shows that the occurrence scattering time advance decreases with an increase of the Dupree diffusivity. Hence, we have found that the influence of plasma turbulence diminishes the occurrence time advance in forward electron-ion collisions in thermal turbulent plasmas. The occurrence time advance shows that the propensity of the occurrence time advance increases with increasing scattering angle. It is also found that the effect of turbulence due to the Dupree diffusivity on the occurrence scattering time advance decreases with an increase of the thermal energy. In addition, the variation of the plasma turbulence on the occurrence scattering time advance due to the plasma parameters is also discussed.

Influence of the dynamic plasma shielding on the elastic electron-ion collision in turbulent plasmas

Journal Article Jung, Young-Dae - Applied Physics Letters

The dynamic plasma shielding effects on the elastic electron-ion collision are investigated in turbulent plasmas using the second-order eikonal method. The results show that the dynamic screening effect strongly enhances the eikonal phase shift as well as the cross section. It is also found that the dynamic screening effect decreases with increasing impact parameter. In addition, the influence of the turbulence suppresses the eikonal phase shift and cross section, especially, for small impact parameters. Moreover, it is found that the dynamic screening effect on the eikonal cross section increases with decreasing thermal energy for large impact parameters.

Journal Article Jung, Young-Dae; Hong, Woo-Pyo - Physics of Plasmas

The effects of ion temperature on the occurrence scattering time for the electron-dust grain collision are investigated in dusty plasmas. The Eikonal analysis is applied to obtain the scattering amplitude and occurrence scattering time for the electron-dust collision. It is found that the occurrence scattering time represents the oscillatory behavior. It is also found that the amplitude and oscillation interval of the occurrence scattering are enhanced with increasing collision energy. It is found that the ion temperature effect suppresses the occurrence scattering time in three-component dusty plasmas. It is also found that the density effect reduces the occurrence scattering time.

Quantum diffraction effects on the atomic polarization collision in partially ionized dense plasmas

Journal Article Jung, Young-Dae - Physics of Plasmas

The influence of quantum diffraction on the electron-atom polarization collision process is investigated in partially ionized dense plasmas. The pseudopotential model and eikonal method are employed to obtain the eikonal phase shift and eikonal cross section as functions of the impact parameter, collision energy, Debye length, electron de Broglie wavelength, and atomic polarizability. The results show that the eikonal phase shift for the electron-hydrogen atom polarization collision decreases with an increase of the electron de Broglie wavelength.
