Production, characterization and operation of $$^{76}$$ 76 Ge enriched BEGe detectors in GERDA

Search for neutrinoless double-beta decay of Ge-76 with GERDA

Gerda, the GERmanium Detector Array experiment, is a new double beta-decay experiment which is currently under construction in the INFN National Gran Sasso Laboratory (Lngs), Italy. It is implementing a new shielding concept by operating bare Ge diodes enriched in Ge-76 in high purity liquid argon supplemented by a water shield. The aim of Gerda is to verify or refute the recent claim of discov...

Feasibility study of the observation of the neutrino accompanied double beta - decay of 76 Ge to the 0 + 1 - excited state of 76 Se using segmented germanium detectors

Neutrinoless ββ matrix element of 76 Ge from spectroscopic data

In this work we use the recently measured neutron pairing correlations in the 76 Ge and 76 Se nuclei as a guideline to adjust the single-particle energies in the 1p0f0g shell. The resulting BCS occupations reproduce the measured pairing data. The proton energies were inspected by using the odd-mass nuclei adjacent to 76 Ge and 76 Se as spectroscopic tools. The nuclear matrix element of the neut...

Biological vesicles are composed of a phospholipid membrane bi-layer, which has folded on itself to form a spherical structure with an aqueous cavity. We propose that synthetic vesicles, termed liposomes, composed of speciic species of phospholipids might provide a useful architecture for the execution of some existing algorithms for DNA based computation. In this model, the liposomes would ser...

Spectroscopy and lifetime measurements of states in 76 Kr populated in 76 Rb decay

The properties of the excited states of 76Kr, populated in the decay of 76Rb produced at ISOLDE isotopic separator, have been investigated by using K-conversion electron, γ -ray, and γ -γ coincidence measurements. The lifetimes of several levels have been measured by means of the advanced time-delayed βγ γ (t) method. The identification of 19 new levels and 55 transitions and the information de...
