Long-time self di usion coe cient is calculated over a broad range of densities from computer
simulations of a two-dimensional system obeying Brownian dynamics and interacting through a
Yukawa pairwise potential. The behavior of the di usion under changes of strength of the potential
and density of particles is discussed and compared with bibliographical results. Furthermore, the
e ects of an external driving force and the presence of  xed particles are also considered. It is found
that the di usion lowers with the density of particles, the strength of the potential and the presence
of  xed particles. On the contrary, an external force favors the di usion. Despite the e ect of the external force, a jammed state can be reached if density and proportion of  xed particles are high enough.
