Results of the experiment on investigation of Germanium-76 double beta decay. Experimental data of Heidelberg-Moscow collaboration November 1995 - August 2001

On the termination of the Heidelberg-Moscow double-beta decay of Germanium-76 experi-ment, the analysis of the obtained data is presented. The value of the half-life for two-neutrino double beta decay (2b2n mode) and limitation of the half-life for neutrinoless dou-ble beta decay (2b0n mode) are given. The results were presented at NANP2003, Dubna, June, 24.

Identification of single events in the HPGe detector: Comparison of various methods based on the analysis of simulated pulse shapes

Various methods of identification of single events in the HPGe detector are compared on the basis of a program especially designed to simulate pulse shape in a semi-conductor germanium detector. Capabilities of three following methods are shown: (1) an application of the library of single pulse shapes, (2) the single-parameter method, and (3) a separation on the basis of artificial neural networks. The analysis was done in the context of an application of all above-mentioned techniques in the energy interval around the expected neutrino less double beta decay of Ge-76 in the Heidelberg-Moscow experiment.
