Abstract
Inelastic neutron scattering with polarisation analysis has been used to investigate the critical long wavelength spin fluctuations in Rb2CrCl4. As well as spin wave and central peak components expected from fluctuations within the easy plane, weak central peak components are observed which may result from the diffusion of spin vortices.
