摘要：

A computation code is presented, allowing numerical simulation and pulse-shape analysis of the ionization and heat signals in low-temperature massive Ge detectors for Dark Matter research. The effects on charge collection are pointed out, arising from the Coulomb repulsion of free carriers within the charge clouds. Test experiments are described, aimed at event localization for improved background rejection. (C) 2003 Elsevier B.V. All rights reserved.
