The new screening characteristics of strongly non-ideal and dusty plasmas. Part 3: Properties and applications

Abstract

The physical sense and the properties of a group screening parameters which are determined in the previous papers (Part 1 and Part 2) for single-and two-component systems is discussed in this paper. On the base of data from the mentioned papers are determined two new characteristic lengths which complete a new hierarchy system of screening lengths in plasma. It was shown that the methods developed in Part 1 and Part 2 generates results which are applicable to the strongly non-ideal gaseous and dusty plasmas, and manifest a very good agreement with the existing experimental data.

The Screening Characteristics of the Dense Astrophysical Plasmas: The Three-Component Systems

“…In the subsequent considerations, several characteristic lengths are used that are connected with the parameters N 1,2,e and Z 1,2 , namely, the Wigner-Seit's (WS) radii and the "ion self-spheres" radii (see [3]), denoted here by r 1,2,e and r s;1,2 , respectively. These are defined by the relations…”

“…where x = κ e r e , r κ;e ≡ 1/κ e , and the coefficients γ s;e (x) and γ κ;e (x) are connected with the electron non-ideality parameters Γ e = e 2 /(kT e r e ) and γ e = e 2 /(kT e r κ;e ) as described in [3].…”

“…Thematically, this work is the natural extension of the research on plasma's inner electrostatic screening, the results of which are presented in the papers [1][2][3]. In these papers, the single-and two-component systems are discussed with their properties in the region of higher non-ideality degree.…”

“…This has all induced the interest for the possibility of going beyond the sphere of influence of [13] and for the development of the mentioned alternative method. Additionally, another stimulus exists for the development of alternative methods, connected with finding a characteristics length greater than the Debye radius ( [30][31][32][33][34][35]; see also [3]). …”

“…The developed theory is also applicable to a wider area of plasma parameters. The order of its exposing mostly follows that which is presented in our previous papers [1][2][3].…”
