From ASAXS measurements partial pair correlations can be determined both in the fluctuations [MATH] of the local concentrations [MATH] of the ith species and in the fluctuations [MATH] of the local number density of all kinds of atoms. This requires a separation of the measured intensity into partial intensities which depend linearly on the squared average atomic form factor, form factor differences and cross terms. The structural analysis is illustrated for the example of simple 2-phase models.
