Opis:: The radioactive isotope $^{85}$Kr is found in significant quantities in the atmosphere largely due to nuclear industry. Its β-decay with a half-life of 10.7 years and a Q-value of 687 keV is a dangerous background source for low-threshold noble gas and liquid detectors, which distill their detector medium from air. The Gerda experiment was operating high-purity germanium detectors immersed in a clean liquid argon bath deep underground to search for neutrinoless double beta decay with unprecedented sensitivity. The $^{85}$Kr specific activity in the liquid argon at the start of the second phase of the experiment has been determined to be (0.36 $\pm$ 0.03) mBq/kg through an analysis of the full subsequent data set that exploits the excellent γ-ray spectroscopic capabilities of GERDA.

Opis:: The GERmanium Detector Array (Gerda) experiment operated enriched high-purity germanium detectors in a liquid argon cryostat, which contains 0.33% of $^{36}$Ar, a candidate isotope for the two-neutrino double-electron capture (2$\nu$ECEC) and therefore for the neutrinoless double-electron capture (0$\nu$ ECEC). If detected, this process would give evidence of lepton number violation and the Majorana nature of neutrinos. In the radiative 0$\nu$ECEC of $^{36}$Ar, a monochromatic photon is emitted with an energy of 429.88 keV, which may be detected by the Gerda germanium detectors. We searched for the $^{36}$Ar 0$\nu$ECEC with Gerda data, with a total live time of 4.34 year (3.08 year accumulated during Gerda Phase II and 1.26 year during Gerda Phase I). No signal was found and a 90% CL lower limit on the half-life of this process was established T$_{1/2}$ > 1.5 · 10$^{22}$ year.

Opis:: The beta decay of $^{77}$Ge and $^{77m}$Ge, both produced by neutron capture on $^{76}$Ge, is a potential background for Germanium based neutrinoless double-beta decay search experiments such as GERDA or the LEGEND experiment. In this work we present a search for $^{77}$Ge decays in the full GERDA Phase II data set. A delayed coincidence method was employed to identify the decay of $^{77}$Ge via the isomeric state of $^{77}$As (9/2$^{+}$, 475 keV, T$_{1/2}$ = 114 μs, $^{77m}$As). New digital signal processing methods were employed to select and analyze pile-up signals. No signal was observed, and an upper limit on the production rate of $^{77}$Ge was set at < 0.216 nuc/(kg $\cdot$ yr) (90% CL). This corresponds to a total production rate of $^{77}$Ge and $^{77m}$Ge of < 0.38 nuc/(kg $\cdot$ yr) (90% CL), assuming equal production rates. A previous Monte Carlo study predicted a value for in-situ $^{77}$Ge and $^{77m}$Ge production of (0.21 ± 0.07) nuc/(kg $\cdot$ yr), a prediction that is now further corroborated by our experimental limit. Moreover, tagging the isomeric state of $^{77m}$As can be utilised to further suppress the $^{77}$Ge background. Considering the similar experimental configurations of LEGEND-1000 and GERDA, the cosmogenic background in LEGEND-1000 at LNGS is estimated to remain at a sub-dominant level.

Opis:: A search for full energy depositions from bosonic keV-scale dark matter candidates of masses between 65 and 1021 keV has been performed with data collected during Phase II of the GERmanium Detector Array (Gerda) experiment. Our analysis includes direct dark matter absorption as well as dark Compton scattering. With a total exposure of 105.5 kg years, no evidence for a signal above the background has been observed. The resulting exclusion limits deduced with either Bayesian or Frequentist statistics are the most stringent direct constraints in the major part of the 140–1021 keV mass range. As an example, at a mass of 150 keV the dimensionless coupling of dark photons and axion-like particles to electrons has been constrained to $\alpha' / \alpha$ < 8.7 $\times$ 10$^{-24}$ and g$_{ae}$ < 3.3 $\times$ 10$^{-12}$ at 90% credible interval (CI), respectively. Additionally, a search for peak-like signals from beyond the Standard Model decays of nucleons and electrons is performed. We find for the inclusive decay of a single neutron in $^{76}$Ge a lower lifetime limit of $\tau_{n}$ > 1.5 $\times$ 10$^{24}$ years and for a proton $\tau_{p}$ > 1.3 $\times$ 10$^{24}$ years at 90% CI. For the electron decay e$^{-} \to \nu_{e}\gamma$ a lower limit of $\tau_{e}$ > 5.4 $\times$ 10$^{25}$ years at 90% CI has been determined.
