Natural orbitals in multiconfiguration calculations of hyperfine-structure parameters

Relativistic calculations of pionic and kaonic atoms hyperfine structure

Localized orbitals for molecular calculations

We present an overview of the existing localization algorithms which have been or are being used to perform quantum chemical molecular calculations that take into account electronic correlation effects. The natural distinction between intrinsic and extrinsic localization methods is explained and developed. The advantages and drawbacks of specific methods are discussed in terms of CPU time requi...

the role of thematic structure in comprehending spoken language

in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...

Storage-ring measurement and multiconfiguration Dirac-Fock calculations

The electron-ion recombination rate coefficient for Si IV forming Si III was measured at the heavyion storage-ring TSR. The experimental electron-ion collision energy range of 0–186 eV encompassed the 2p nl n′l′ dielectronic recombination (DR) resonances associated with 3s→ nl core excitations, 2s 2p 3s nl n′l′ resonances associated with 2s → nl (n = 3, 4) core excitations, and 2p 3s nl n′l′ re...
