The first eight l = 0, 1, 2 orbitals and the first seven l = 3 orbitals were used in standard two-electron configuration-interaction (CI) calculations. The set of all possible two-electron antisymmetric configurations of the form 3snl and 3pnl were built, resulting in 210 configurations. ...
Full size image Bond strength can be approximatively estimated by the force constant. The average force constant of Mg,\(\left\langle F\right\rangle\)(in N/m) was calculated and shown in Table2and Table3. At high temperatures where the frequencies related to the element of interest\(\nu...

Helium is considered a key tracer for processes in Earth’s deep interior as the core is thought to be a reservoir for the primordial isotope 3He. High 3He/4He ratios in ocean island basalts fed by mantle plumes are indicative of relatively undegassed re
Transmission electron microscopy (TEM) imaging was obtained with a JEOL JEM 2010 microscope operating at 200 kV (0.19 nm resolution), provided with an EDS system, INCA Energy TEM 100 X-Max 65 T. Cross-sectional samples were prepared in Cu2O:Mg film on silicon by tripod polishing resulting ...
