The calculation is performed by the relativistic configuration-interaction method adapted for treatment of autoionizing core-excited states. The calculational approach includes the relativistic treatment of the nuclear recoil effect, the leading QED shifts as delivered by the model QED operator, and the frequency dependence of the Breit interaction. The $1s2l2l'-1s^22l$ transition energies are obtained by combining the present results for the $1s2l2l'$ states with energies of the $1s^22l$ states compiled from previous calculations. All theoretical energies are supplied with uncertainty estimates. Our theoretical predictions for the $1s2l2l'-1s^22l$ transitions are significantly more accurate than the best experimental results available today and can be used for calibrating experimental X-ray spectra.","PeriodicalId":16783,"journal":{"name":"Journal of Physical and Chemical Reference Data","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1063/1.5034574","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48988955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The contributions for the zero-density viscosity and for the initial-density dependence were separately developed, whereas those for the critical enhancement and for the higher-density terms were pretreated. All contributions were given as a function of the reciprocal reduced temperature τ, while the last two contributions were correlated as a function of τ and of the reduced density δ. The different contributions were based on specific primary data sets, whose evaluation and choice were discussed in detail.
