“…It can be noted that our results of the ex-cited states for Li, Na, K, and Rb are consistent with allorder method, [42,50,53] RCCSD(T), [43] RMBPT [47] results, and the available experimental values considering their uncertainties. [13,16,45,46,48,49,51,52] For Cs atoms, our results are in agreement with all-order results [54] and the experimental values [55][56][57][58][59] in their uncertainties. The polarizabilities of the excited states for Fr atom, to our knowledge, are the first reported results.…”

“…Laser frequency was not a perfectly linear function of scan voltage, so the positions of the four observed peaks were used as markers to calibrate each scan. The 2s hyperfine splitting (228.2 MHz in 6 Li and 803.5 MHz in 7 Li [10]) and the 3d fine structure splitting (1084.2 MHz in 6 Li [11] and 1083.9 MHz in 7 Li [12]) were used for this purpose. The maximum resulting correction was about 5%.…”

We report measurements of the foreign gas line broadening rate for the 2s-3d transition in 6 Li and 7 Li with the rare gas perturbers neon and argon. We compare our measurements with calculations made in the impact approximation using both ab initio diatomic potentials and long-range coefficients. Agreement is in all cases better than 30%. As in our previous study of Li 2s-3s broadening, we find that the available potentials do not agree well at intermediate range. Improved agreement will likely require improved potentials as well as a more sophisticated model.

Temperature‐Dependent Morphology, Magnetic and Optical Properties of Li‐Doped MgO

et al. 2010

Li-doped MgO is a potential catalyst for the oxidative coupling of methane, whereby surface Li+ O- centers are suggested to be the chemically active species. To elucidate the role of Li in the MgO matrix, two model systems are prepared and their morphological, optical and magnetic properties as a function of Li doping are investigated. The first is an MgO film deposited on Mo(001) and doped with various amounts of Li, whereas the second is a powder sample fabricated by calcination of Li and Mg precursors in an oxygen atmosphere. Scanning tunneling and transmission electron microscopy are performed to characterize the morphology of both samples. At temperatures above 700 K, Li starts segregating towards the surface and forms irregular Li-rich oxide patches. Above 1050 K, Li desorbs from the MgO surface, leaving behind a characteristic defect pattern. Traces of Li also dissolve into the MgO, as concluded from a distinct optical signature that is absent in the pristine oxide. No electron paramagnetic resonance signal that would be compatible with Li+O- centers is detected in the two Li/MgO samples. Density-functional theory calculations are used to determine the thermodynamic stability of various Li-induced defects in the MgO. The calculations clarify the driving forces for Li segregation towards the MgO surface, but also rationalize the absence of Li+O- centers. From the combination of experimental and theoretical results, a detailed picture arises on the role of Li for the MgO properties, which can be used as a starting point to analyze the chemical behavior of the doped oxide in future
