Neutrinoless double beta decay is a process that violates lepton number conservation. It predicted to occur in extensions of the standard model particle physics. This Letter reports results from phase I Germanium Detector Array (GERDA) experiment at Gran Sasso Laboratory (Italy) searching for neutrinoless isotope $^{76}\mathrm{Ge}$. Data considered present analysis have been collected between November 2011 and May 2013 with total exposure 21.6 kg yr. A blind performed. The background index...
The GERDA experiment searches for the lepton-number-violating neutrinoless double-β decay of ^{76}Ge (^{76}Ge→^{76}Se+2e^{-}) operating bare Ge diodes with an enriched fraction in liquid argon. exposure broad-energy germanium type (BEGe) detectors is increased threefold respect to our previous data release. BEGe feature excellent background suppression from analysis time profile detector signals. In window a level 1.0_{-0.4}^{+0.6}×10^{-3} counts/(keV kg yr) has been achieved; if normalized...
Absolute cross sections for isotopically identified products formed in multinucleon transfer the (136)Xe+(198)Pt system at ∼8 MeV/nucleon are reported. The isotopic distributions obtained using a large acceptance spectrometer demonstrated production of "hard-to-reach" neutron-rich isotopes Z<78 around N=126 shell closure far from stability. main contribution to formation these exotic nuclei is shown arise collisions with small kinetic energy dissipation. present experimental finding...
The extinct p-process nuclide 146Sm serves as an astrophysical and geochemical chronometer through measurements of isotopic anomalies its alpha-decay daughter 142Nd. Based on analyses 146Sm/147Sm alpha-activity atom ratios, we determined the half-life to be 68 \pm 7 (1sigma) million years (Ma), which is shorter than currently used value 103 5 Ma. This implies a higher initial abundance in early solar system, (146Sm/144Sm_0 = 0.0094\pm0.0005 (2sigma), previously estimated. Terrestrial, Lunar...
A discovery that neutrinos are not the usual Dirac but Majorana fermions, i.e. identical to their antiparticles, would be a manifestation of new physics with profound implications for particle and cosmology. generate neutrinoless double-$\beta$ ($0\nu\beta\beta$) decay, matter-creating process without balancing emission antimatter. So far, 0$\nu\beta\beta$ decay has eluded detection. The GERDA collaboration searches $0\nu\beta\beta$ $^{76}$Ge by operating bare germanium detectors in an...
A modern variation of the Rutherford experiment to probe tunneling exotic nuclear matter from measurement residues formed in bombardment (197)Au by extremely neutron-rich (8)He nuclei is presented. Using a novel off-beam technique most precise and accurate measurements fusion neutron transfer involving reaccelerated unstable beams are reported. The results show unusual behavior compared that for lighter helium isotopes, highlighting role intrinsic structure composite many-body quantum...
The lifetimes of the first excited $2$${}^{+}$ states in $^{62}\mathrm{Fe}$ and $^{64}\mathrm{Fe}$ have been measured for time using recoil-distance Doppler shift method after multinucleon transfer reactions inverse kinematics. A sudden increase collectivity from to is observed. experimental results are compared with new large-scale shell-model calculations Hartree-Fock-Bogolyubov--based configuration-mixing Gogny D1S interaction. give a deeper understanding mechanism leading an onset near...
A search for neutrinoless $\beta\beta$ decay processes accompanied with Majoron emission has been performed using data collected during Phase I of the GERmanium Detector Array (GERDA) experiment at Laboratori Nazionali del Gran Sasso INFN (Italy). Processes spectral indices n = 1, 2, 3, 7 were searched for. No signals found and lower limits order 10$^{23}$ yr on their half-lives derived, yielding substantially improved results compared to previous experiments $^{76}$Ge. new result half-life...
The GERmanium Detector Array (GERDA) experiment at the Gran Sasso underground laboratory (LNGS) of INFN is searching for neutrinoless double beta decay 76Ge. signature signal a monoenergetic peak 2039 keV, Q-value decay, Q_bb. To avoid bias in search, present analysis does not consider all those events, that fall 40 keV wide region centered around main parameters needed are described. A background model was developed to describe observed energy spectrum. contains several contributions,...

The GERDA experiment located at the LNGS searches for neutrinoless double beta (0\nu\beta\beta) decay of ^{76}Ge using germanium diodes as source and detector. In Phase I eight semi-coaxial five BEGe type detectors have been deployed. latter is used in this field research first time.

The GERmanium Detector Array (Gerda) at the Gran Sasso Underground Laboratory (LNGS) searches for neutrinoless double beta decay ( $$0\nu \beta $$ ) of $$^{76}$$ Ge. Germanium detectors made material with an enriched Ge fraction act simultaneously as sources and this decay. During Phase I theexperiment mainly refurbished semi-coaxial from former experiments were used. For upcoming II, 30 new broad energy germanium (BEGe)-type produced. A subgroup these has already been deployed in Gerda...
Time-resolved imaging with penetrating radiation has an outstanding scientific value but its realisation requires a high density of photons as well corresponding fast X-ray image detection schemes. Bending magnets and insertion devices third generation synchrotron light sources offer polychromatic photon flux which is enough to perform hard spatio-temporal resolution up the μm-μs range. Existing indirect detectors commonly used at can be adapted for acquisition by employing CMOS-based...
