Abstracts

EN

Measurement of absorption and propagation velocity of ultrasonic waves as well as shear viscosity in n-amylic alcohol-nitromethane critical mixture are reported. Acoustic measurements were performed in the frequency range from 5 to 25 MHz and temperatures ΔT = T - T_{c} from 0.1 to 12.3 K. An analysis of the results was carried out on the basis of a modified version of mode-coupling theory [10], which led to good agreement with experiment. The correlation length ξ_{0} = 0.94 Ǻ is in agreement with the value obtained from optical measurements.
