Small angle neutron scattering has been used to investigate the vortex scattering in single crystal niobium. In the mixed state (Hc1HHc2) a sixfold hexagonal pattern of peaks is observed at all temperatures. Below the irreversibility line these peaks are resolution limited, while above it the width in the transverse direction increases with temperature due to the vortex dynamics. Close to Hc2 the radial widths of the peaks also broaden. However, the basic hexagonal pattern of peaks is maintained throughout, indicating that a correlated flux fluid exists in the reversible regime.
