Abstract
For the first time a search for dark matter with isotopically enriched material is done, by using the Ge detectors of the Heidelberg-Moscow experiment. A measuring time of 165.6 kg.d is used to set limits on th e spin-independent cross section of weakly interacting massive particl es (WIMPs). A background level of 0.102+/-0.005 events/(kg.d.keV) was achieved (average value between 11 keV and 30 keV). It was possible to extend the exclusion range for Dirac neutrino masses up to 4.7 TeV.
