Abstract
It is shown that a noninteracting—spin-wave theory, in which the central component observed by neutron scattering is attributed to scattering from spin-wave—density fluctuations, gives intensities comparable to, or greater than, the intensities predicted by the soliton theory, and provides a better fit to the variation of the intensity with field, temperature, and wave vector. It is concluded that further work is needed to distinguish the soliton contribution to the central-peak intensity from the scattering by pairs of spin waves.Keywords
