The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

SINOPSIS

The present work is focused on parametric computations of electron energy distribution function (EEDF) and electron mobility in resonant photo-plasma of sodium mixed with argon and molecular nitrogen. The conditions of a weak external electric field are considered, when electron heating is provided by collisions of the second kind with excited sodium atoms. It is shown that the non-equilibrium shape of the EEDF arising in this mixture can considerably affect electron mobility. It is demonstrated that under certain conditions the mobility may have negative values. The critical plasma parameters (partial pressure of mixture components, plasma ionization degree (ε), population of excited sodium atoms, electric reduced field strength, vibration temperature of nitrogen molecules) are elucidated.
