WebDec 1, 1978 · The absorption spectra of two specmens of KC1 containing 2 mole % ofBr and Rb, respectively, have also been measured in the range 90-130 cm-1, but no impurity-induced spectral structure was found. A similar investigation of RbBr specimens containing K and Cl impurities also failed to reveal any new structure in the spectral range 30-80 cm-1.

WebJan 1, 1978 · The role of Rb + ions on defect formation in KBr has been studied. The impurity suppresses colorability due to X-raying at 6 K, but does not result in the formation of any centers characteristic to Rb + ions at this temperature. A new optical absorption band peaked at 3.19 eV is produced only by thermal annealing of irradiated KBr:Rb.

We ascribe this to inelastic scattering of vibrating dislocations. At the same time the suppression of phonon drag at higher temperatures results in the emergence of the normal electron …
WebInorganic impurities often derive from the manufacturing process. These impurities are often reagents, ligands, catalysts, heavy or residual metals, inorganic salts, filter aids, or charcoals. Inorganic contaminants can be detected and quantified using pharmacopeial standards. Importance of Impurity Study WebAbstract. We report the progress on investigating the Bose polaron problem with a mixture of ultracold Bose-Bose mixture of 23 Na and 87 Rb atoms. We prepare the Bose polaron by immersing heavy 87 Rb impurities in the Bose-Einstein condensate of 23 Na. Using radio frequency spectroscopy, we investigate the polaron injection spectrum and its …
