Electrical conductivity and scattering sections of strongly coupled hydrogen plasmas

Scattering processes and electrical conductivity of partially ionized hydrogen plasma

“…Correlation effects become important with increasing density of the plasma. Especially, three-particle correlations have been shown to be important for the transport and thermodynamics properties of fully ionized, nonideal plasmas [3,4,5,16,17] which were treated using the effective potential (1). Therefore, we study the influence of such three-particle correlations on the ionization equilibrium (11) by calculating the ground state energies with respect to the effective potential (1).…”

“…This problem can be solved by considering the screening between the charged particles via the dielectric function of the medium which leads to effective, density and temperature dependent potentials. Both dynamic [1,2] and static screening effects [3,4] have been studied for nonideal plasmas.…”

Scattering Cross Sections and Electrical Conductivity in Fully Ionized Hydrogen Plasma

“…In [6] we have studied the scattering processes between the particles in weakly nonideal plasmas with y 5 0.7 using an upprozimate analytical expression for the effective potential…”

Micro-Radiographs Stored in Lithium Fluoride Films Observed by Scanning Near-Field Optical Microscopy

“…In high-density plasmas, the multiparticle correlation effects caused by simultaneous interaction of many charged particles must be taken into account. In these circumstances, the interaction potential would not be described by the Debye-Hückel model due to the strong collective effects of nonideal particle interactions [13][14][15][16]. However, the threshold behavior of the ionization cross-section for the two-electron escape in classical nonideal plasmas has not been specifically investigated.…”

“…Recently, an integro-differential equation for the effective screened potential [13,14] of the particle interaction taking into account the simultaneous correlations of many particles has been derived on the basis of a sequential solution of the chain of Bogolyubov equations for the equilibrium distribution function of particles of nonideal plasmas and the simple analytic expression for the pseudopotential of the particle interaction has been obtained by the splineapproximation. Using the pseudopotential model taking into account the collective and plasma screening effects, the effective electron-ion (Z) interaction potential [13] V e-Z (r) in classical nonideal plasmas can be obtained as…”
