The frequency and damping of ion-acoustic waves in a singly ionized plasma have been determined for wave lengths at which collisions are important but not dominant and for electron-ion temperature ratios of 0.5, 1, 2, and 4, by numerically solving the linearized Fokker--Planck equation. The collisional and collisionless limits are in good agreement with existing theory. As a by-product the ion viscosity and thermal conductivity were evaluated and agreed with those of Braginskii.
