More specifically, results of the two methods were found to agree well (Dif. < 10 %) for air, calcium fluoride, kapton polyimide film, paraffin wax and plastic scintillator in the entire energy region with respect to the total electron interaction. On the other hand, values for Z (eff) ...
The coordination of the berkelium atom in its trivalent fluoride and chloride is tricapped trigonal prismatic, with a coordination number of 9. WikiMatrix is an alkyl residue with 4-8 C-atoms and n is a number from 5 to 9; 2) 10-90 % by wt., relative to the combination of active...
In addition, AFM single-atom manipulation can be applied to nonconductive materials as well, such as calcium fluoride (CAF2) [100]. A comprehensive review was done by Custance et al [96] that summarized AFM for atom manipulation. Although still in its early stage development, atom ...
45. The micro-comb was excited with a self-injection mechanism in a WGM resonator in calcium fluoride to keep the optical pump locked to one of the resonator lines, as discussed in Section 6. The optical pump used was eventually locked to the 87Rb transition by thermally modulating the ...
Xenon hexafluoride is both a strong fluoride-ion donor and a strong fluoride-ion acceptor. Examples of salts containing the XeF5+cation are numerous, with counter anions such as PtF6−and AuF6−. Examples of salts containing the fluoride bridged Xe2F11+cationare also known. Xenon hexafluorid...
