Stimulated by recent high-resolution neutron data from ILL, we have carried out an extensive numerical study of the single-particle pa (Q, w) and the two-particle p2 (Q, w) spectral densities within the well known Ruvalds and Zawadowsld (ZS) scenario, over a wide range of wavevectors (1 < Q < 3~-1),
