Pl. Elliott et al., MODES OF TRANSVERSE RESPONSE IN A 2-DIMENSIONAL COULOMB SYSTEM ABOVE THE MELTING TEMPERATURE, Physica. B, Condensed matter, 251, 1998, pp. 664-667
Experiments are described that were designed to measure the viscosity
of a 2D Coulomb fluid formed from helium ions trapped below the free s
urface of superfluid helium, especially at temperatures just above mel
ting. The results and limitations of these experiments are discussed,
and new effects associated with steps in the density profile are descr
