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

ABSTRAKT

Noisy and spectrally not well resolved molecular emission spectra of the 516.611 nm Swan band of the C2 molecule were employed for evaluation of the rotational temperature in different plasma sources. This diagnostic method may be applied in the temperature range from 300K to 6000K. It is especially useful when the apparatus function of a recording system is unknown The described method is based on a comparison of experimental data with the theoretically calculated spectrum. The numerical minimisation procedure is started with the temperature value obtained from the Boltzmann plot or intensity ratio of two selected spectrum components. A particular attention was paid to this point because it seems, that the departure from the local thermodynamic equilibrium (LTE), observed by several authors, can be due to an error in data evaluation. La bande de Swan C2(d3Πgv'=0) → C2(a3Πu,v"=0) a 516.611 nm, bruitee et spectralement mal resolue. pent etre employee pour evaluer la temperature rotationnelle dans differents generateurs de plasma, dans une gamme etendue de temperature (jusqu 'a 6000K). La methode decrite est basee sur la comparaison des donnees experimentales avec un spectre theorique, la procedure numerique etant initiee a I'aide d'une premiere estimation de la temperature obtenue a partir d'un graphe de Boltzmann, ou en utilisant une "fonction test". Une attention particuliere est faite pour distinguer un eventuel ecart a l'equilibre thermodynamique local (ETL) des eventuelles erreurs de traitement des donnees...
