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),

The cross section for light scattering from superfluid helium in which bound roton pairs are created is calculated in a simple model, taking into account both the excitations themselves and their coupling to the light. It is shown that the depolarization ratios from bound and from noninteracting rot
