摘要：

The IGEX experiment has been operating enriched germanium detectors in the Canfranc Underground Laboratory (Spain) in a search for the neutrinoless double decay of Ge-76. The implementation of pulse-shape discrimination techniques to reduce the radioactive background is described in detail. This analysis has been applied to a fraction of the IGEX data, leading to a rejection of similar to60% of their background, in the region of interest (from 2 to 2.5 MeV), down to similar to0.09 c/keV kg yr.
