Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract Radial distribution functions of dusty plasma particles are calculated by the application of the Langevin dynamics to a system of particles interacting through the Yukawa potential. Proposed numerical model is first validated by the comparison of the numerical results with available experimental data. Both numerically determined and experimental radial distribution functions demonstrate a good coincidence, thus, enabling a calculation of the structural properties of dusty plasma for a wide range of parameters. On the basis of the performed calculations, dependencies of internal energy and excess pressure from the coupling and density parameters are presented (© 2009 WILEY‐VCH Verlag GmbH & Co.
