Websion L, the Born approximation becomes less accu-rate, as seen in the large-kL regions of Figs. 1(a) and 1(b). In summary, the Born approximation is valid for sample sizes that are larger than l c (for adequate spatial averaging) and smaller than l s (for single scattering.) If no such range for L exists [as in Fig. 1(b)], the Born ... WebThe BO approximation recognizes the large difference between the electron mass and the masses of atomic nuclei, and correspondingly the time scales of their motion. Given the …
