Dispersion of the F+2 center in KCl crystal [PDF]
Solid State Communications, 1985 Abstract The dispersion due to F+2 center in KCl crystal is determined at liquid helium temperature through an ellipsometric technique using their polarization properties in the spectral region of the ls g→2p u transition. The maximum index change expressed as a function of the peak-to-peak dichroic absorption constant αd(cm−1) is given by (n ...
