Self-diffusion has been experimentally studied in a two-dimensional underdamped liquid complex (dusty) plasma. It was found that the self-diffusion coefficient D increases linearly with the temperature T: D/{omega}{sub E}a{sup 2}=(0.019{+-}0.007)(T/T{sub m}-1), where T{sub m}, {omega}{sub E}, and a are the melting temperature, the Einstein frequency, and the mean particle separation, respectively. No superdiffusion was observed, whereas a subdiffusion occurred at temperatures close to melting.
