Scattering Cross Sections and Electrical Conductivity in Fully Ionized Hydrogen Plasma

Abstract

The cross sections for the scattering of charged particles in hydrogen plasma are determined within the partial wave method. The scattering phase shifts 61 are obtained from a numerical solution of the Schrijdinger equation using an effective potential that takes into account also three-particle correlations. The resulting scattering cross sections are compared with the respective Born approximation and those obtained for the usual Debye potential which represents only two-particle correlations. Furthermore, the electrical conductivity of f d y ionized hydrogen plasma is determined within the Chapman-Enskog method and compared with available experimental data and other theoretical approaches up to the nonideal region.

Electrical conductivity of plasmas of DB white dwarf atmospheres

“…One of the most frequently used approximations for consideration of transport properties of different plasmas is the approximation of ‘fully ionized plasma’ (Spitzer 1962; Radke et al 1976; Adamyan et al 1980; Kurilenkov 1984; Ropke & Redmer 1989; Djuric et al 1991; Nurekenov et al 1997; Zaika, Mulenko & Khomkin 2000; Esser, Redmer & Ropke 2003). It was shown that the electrical conductivity of fully ionized plasmas can be successfully calculated using the modified random‐phase approximation (RPA) (Djuric et al 1991; Adamyan et al 1994a,b) in the region of strong and moderate non‐ideality, while the weakly non‐ideal plasmas were successfully treated within the semiclassical approximation (SC) (Mihajlov et al 1993; Vitel et al 2001).…”

Electron transfer in proton‐hydrogen collisions in nonideal classical plasmas

“…Relating to NCP, there are a number of studies in which the pseudopotential (Equation 2) has been used to represent the particle interactions in NCPs. [38][39][40][41][42][43][44][45] It should be mentioned that the pseudopotential (Equation 2) does not take care the effects of quantum degeneracy. Quantum mechanical effects come into play when the average interparticle distance is comparable with the thermal de Broglie.…”
