N2 - We have observed a quasi-elastic contribution to the spectrum of the transverse spin fluctuations Sperp;(Q, ω), perpendicular to an applied magnetic field in the easy plane of the one-dimensional ferromagnet CsNiF3. According to the present theoretical understanding this contribution is due solely to soliton quasi-particles and it should not contain two-magnon scattering. The observed dependence on momentum transfer is as expected for soliton scattering with zero intensity at qc = 0 rising through a maximum with increasing qc.
