Abstract
New results after 0.69 kg yr of measurement with an enriched Ge-76 detector of the Heidelberg-Moscow experiment with an active mass of 2.758 kg an pre sented. An energy threshold of 9 keV and a background level of 0.042 cts/(k g d keV) in the energy region between 15 keV and 40 keV was reached. The de rived limits on the weakly interacting massive particles-nucleon cross sect ion are the most stringent limits on spin-independent interactions obtained to date by using essentially raw data without background subtraction.
