标题： Identification of photons in double beta-decay experiments using segmented germanium detectors - studies with a GERDA Phase II prototype detector

摘要： 实验搜索锗的无中微子双β衰变的灵敏度到目前为止受到外部伽马辐射引起的背景的限制。 分段的锗探测器可以用来识别光子，从而减少这一背景成分。 GERmanium Detector Array，GERDA，将在其第二阶段使用高度分段的锗探测器。 使用原型探测器研究光子事件的识别。 结果与蒙特卡罗数据进行比较。 显示英文摘要

摘要： The sensitivity of experiments searching for neutrinoless double beta-decay of germanium was so far limited by the background induced by external gamma-radiation. Segmented germanium detectors can be used to identify photons and thus reduce this background component. The GERmanium Detector Array, GERDA, will use highly segmented germanium detectors in its second phase. The identification of photonic events is investigated using a prototype detector. The results are compared with Monte Carlo data.
