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

摘要

Physical properties of hot dense matter at hundreds GPa pressures are considered. The new experimental results on pressure ionization of hot matter generated by multiple shock compression of hydrogen and noble gases are presented. The low-frequency electrical conductivity of shock compressed hydrogen, helium, and xenon plasmas was measured in the hundred GPa range of pressures. To reduce effects of irreversible heating and implement a quasi-isentropic regime, strongly compressed matter was generated by the method of multiple shock compression in planar and cylindrical geometries. As a result, plasma states at pressures in the hundred GPa range were realized, where the electron concentration could be as high ne ∼ 2×1023 cm−3, which may correspond to either a degenerate or a Boltzmann plasma characterized by a strong Coulomb and a strong inter-atomic interaction. A sharp increase (by three to five orders of magnitude) in the electrical conductivity of strongly nonideal plasma, due to pressure ionization, was recorded, and theoretical models were invoked to describe this increase. Opposite effect was observed for lithium compressed by multiple shock up to pressures ∼ 200 GPa, where electrical conductivity was sharply decreased as pressure increased.
