The authors have investigated the viscosity of liquid {sup 3}He-{sup 4}He mixtures at various {sup 3}He concentrations (0.98% {le} x {le} 9.5%) in the temperature range 1 mK {le} T {le} 100 mK and at pressures 0 bar {le} p {le} 20 bar. At T {le} 10 mK the Fermi-liquid behavior {eta}T{sup 2} = const. as well as {eta} {proportional_to} x{sup 4/3} could be confirmed. However, there are significant deviations from theoretical predictions for the magnitude of the viscosity as well as for its pressure dependence. 6 refs., 3 figs.
