We investigate the magnetoresistance of a weakly density modulated high mobility two- dimensional electron system around filling factor . The density modulation with periods a between 300 nm and 500 nm was generated by in situ interferometric illumination. At low B we found commensurability oscillations of the magnetoresistance characteristic for transport in weak electrostatic potentials ...
