    "abstract": "Measurements with a bare p-type high purity germanium diode (HPGe) submerged\nin a 19 kg liquid argon (LAr) scintillation detector at MPIK Heidelberg are\nreported. The liquid argon--germanium system (LArGe) is operated as a 4$\\pi$\nanti-Compton spectrometer to suppress backgrounds in the HPGe. This R\u0026D is\ncarried out in the framework of the GERDA experiment which searches for\n0$\\nu\\beta\\beta$ decays with HPGe detectors enriched in $^{76}$Ge. The goal of\nthis work is to develop a novel method to discriminate backgrounds in\n0$\\nu\\beta\\beta$ search which would ultimately allow to investigate the\neffective neutrino mass free of background events down to the inverse mass\nhierarchy scale. Other applications in low-background counting are expected.",
