      abstract     = {Anomalous small angle scattering measurements have been
                      applied to diluted solutions ofanionic polyacrylates
                      decorated by specifically-interacting Pb$^{2+}$ cations,
                      revealing partial collapseof the polyacrylate into
                      pearl-like subdomains with a size on the order of a few
                      nanometers. Fromthe pure-resonant scattering contribution of
                      the Pb$^{2+}$ cations, and from subsequent analysis ofthe
                      resonant-invariant, the amount of Pb$^{2+}$ cations
                      condensed onto the polyanions with respect tothe total
                      amount of Pb$^{2+}$ cations in the solvent was estimated. In
                      order to scrutinize systematiclimitations in the
                      determination of the chemical concentrations of resonant
                      scattering counterionsin the collapsed phase, Monte Carlo
                      simulations have been performed. The simulations are basedon
                      structural confinements at variable size in the range of few
                      nanometers, which represent thecollapsed subdomains in the
                      polyanions. These confinements were gradually filled to a
                      high degreeof the volume fraction with resonant scattering
                      counterions giving access to a resonant-invariant ata
                      variable degree of filling. The simulations revealed in the
                      limit of small structures a significantunderestimation of
                      the true degree of filling of the collapsed subdomains when
