A search for no-neutrino double beta decay of /sup 76/Ge using an anticoincidence shielded Ge spectrometer is reported. A new lower limit of T/sub 1/2/ greater than or equal to 1.7 x 10/sup 22/ y at a 90% CL was determined using a maximum likelihood analysis on a 5 keV wide energy bin centered at 2041 keV. Combining this result with the shell model calculations of Haxton, Stephenson and Strottman, we obtain average m/sub nu/ less than or equal to 10 eV and parallel eta parallel less than or equal to 2.4 x 10/sup -5/.
