Spin-orbit splitting of the K band in colored alkali halides

A theoretical calculation of the orbital g‐factor of the excited state of F‐centres in alkali halides

“…The energy separation d between these sublevels has been measured by magneto-optical experiments (see, for instance [I] t o [3]). A was calculated theoretically by Smith for NaCl [4] and for RbCl [5]. Smith's results are in quite good agreement with the experiment.…”

“…5) The wavefunctions Iu4) and [us) derived from a pseudopotential theory are not satisfactory.6) This seems somewhat strange as pseudopotentials have been introduced to improve the point-ion model by taking into account the finite extent of the electronic atmosphere of neighbouring ions. ]u4) and lug) functions turn out to be much more spread out than IuJ and Iuz) (see values of ?/a in Table 2) which causes the too large value of garb.…”

“…,[5] who got good results for A. It does not seem that these approximations should be much worse for the calculation of garb., may be with the exception of approximation 2 b.…”

microARPES and nanoARPES at diffraction-limited light sources: opportunities and performance gains

“…It was already hinted above that self-organized or engineered materials display fluctuations of the electronic properties (including many-body correlations) on the submicrometer spatial scales; it is clear that [as proposed by Smith & Kevan (1991)] it is of tremendous advantage to have a probe at the same spatial scales to determine these position-dependent properties.…”
