Figure 1
Experimentally determined (a) $[f_{As}^{\prime}]$ and (b) $[f_{As}^{\prime\prime}]$ , the real and imaginary resonant scattering of As atoms in InAs bulk, respectively. The $[f_{As}^{\prime\prime}]$ spectrum was obtained from an absorption measurement of an InAs powder using equation (2)

. $[f_{As}^{\prime}]$ is the Kramers–Kronig transform of $[f_{As}^{\prime\prime}]$ calculated using the program DIFFKK (Cross, Newville et al., 1998

). The fine-structure oscillations provide information about the local atomic environment of the resonant atom.
