Unusual temperature dependence of calculated spectra is in agreement with inelastic neutron scattering measurements. Normalized peak intensities of the single-triplet peak are q-independent, their unusual temperature dependence is analyzed in terms of thermodynamic quantities.7 pages, 6 figures in color, submitted to PRBStrongly Correlated Electronstext
