We analyzed the elemental concentrations and the isotopic compositions of helium and argon in Cambrian to Jurrassic aged Gastropod, Ammonite and Trilobite fossils in order to examine variation in thes...
We present here a comprehensive study of the light yield of primary and secondary scintillations produced in gaseous and liquid Ar in the near infrared (NIR) and visible region, at cryogenic temperatu...
A methodology to measure Near Infrared (NIR) scintillations in gaseous and liquid Ar, using Geiger-mode APDs (GAPDs) sensitive in the NIR and pulsed X-ray irradiation, is described. This study has bee...
We investigate the relevance of multiple-orbital and multipole effects during high-harmonic generation (HHG). The time-dependent configuration-interaction singles (TDCIS) approach is used to study the...
The minimum-energy configurations and energetic properties of the ArN-CO2 (N=1-19) van der Waals clusters were investigated by a simulated annealing algorithm. A newly de-veloped Ar-CO2 potential ener...
Abstract: Supersonic-jet luminescence spectroscopy was applied to study vibronic transitions in icosahedral N2 and Ar-N2 clusters having from 100 to 400 particles per cluster. In the case of mixed Ar-...
Infrared scintillation yield in gaseous and liquid argon for rare-event experiments 。
A proof of concept detector is presented for scintillation light detection in liquid argon using Silicon Photo-Multipliers. The aim of the work is to build an anti-Compton veto for germanium detector...
Based on numerical simulations, we show that higher-order nonlinear indices (up to $n_8$ and $n_{10}$, respectively) of air and argon have a dominant contribution to both focusing and defocusing in t...
This paper reports on laser induced multiphoton ionization at 266 nm of liquid Argon in a Time Projection Chamber (LAr TPC) detector. The electron signal produced by the laser beam is a formidable too...
Optogalvanic (OG) spectra of argon in the visible to near-infrared spectral region between 735 and 850 nm were investigated using a Grimm-style glow-discharge tube, which has been widely used to obtai...
In this work, highly charged ions have been extracted from the advanced Electron Beam Ion Source (EBIS-A) developed in a scientific cooperation between the Dresden University of Technology and the DRE...
Recent values of the measured spectral lines Stark widths (since 1988) for neutral and ionized argon atoms, have been compared to the values previously predicted by us. These were found from the est...
The existence of the Stark width dependence on the upper-level ionization potential of the quantum transition have been presented for the four types of transitions (4s’ - 4p’, 4p’ - 4d’, 4p - 5s, 3d...
We have carried out noble gas analysis for gases released by a high-resolution stepwise crushing on basaltic glass and olivine separated from a new set of pillow basalts collected form the Loihi seamo...
