Figure 1
Spectrum of an α-iron foil measured with SMS and the result of fitting with an instrumental function of Lorentzian-squared shape (left) and with an instrumental function extracted from a spectrum of the standard sample (right). The model consists of a sextet related to α-Fe (blue subspectrum), an additional sextet with a smaller magnetic field typical of the presence of residual traces of other metals (red subspectrum), and an asymmetric doublet for the Fe in Be lenses (yellow subspectrum). The green line under the spectra is the residual line. The cyan line shows the quality of the numeric integration (see Section 5[link] below for more details). The result of fitting is presented in the same way as in the GUI of SYNCmoss.
