Binary nucleation of n-octane and i-octane

The authors used a Wilson expansion cloud chamber to measure binary homogen eous nucleation rates for pure n-octane, pure i-octane, and 3:1, 1:1, 1:3 ( mole ratio) mixtures in a temperature range from 215 to 260 K. The nucleati on rates range from approximately 100 to 50 000 drops/cm(3) s. Current bina ry nucleation theory is unable to predict the data for this nearly ideal sy stem.
