Abstract

We have constructed a GEANT4-based detailed software model of photon transport in plastic scintillator blocks and have used it to study the NEMO-3 and SuperNEMO calorimeters employed in experiments designed to search for neutrinoless double beta decay. We compare our simulations to measurements using conversion electrons from a calibration source of $\rm ^{207}Bi$ and show that the agreement is improved if wavelength-dependent properties of the calorimeter are taken into account. In this article, we briefly describe our modeling approach and results of our studies., Comment: 16 pages, 10 figures

Abstract

We report the high-pressure synthesis of novel superconductor MgB$_2$ and some related compounds. The superconducting transition temperature of our samples of MgB$_2$ is equal to 36.6 K. The MgB$_2$ lattice parameters determined via X-ray diffraction are in excellent agreement with results of our ab initio calculations. The time-differential perturbed angular correlation (TDPAC) experiments demonstrate a small increase in quadrupole frequency of $^111$Cd probe with decreasing temperature from 293 to 4.2 K. The electric field gradient (EFG) at the B site calculated from first principles is in fair agreement with EFG obtained from $^11$B NMR spectra of MgB$_2$ reported in the literature. It is also very close to EFG found in our $^111$Cd TDPAC measurements, which suggests that the $^111$Cd probe substitutes for boron in the MgB$_2$ lattice., Comment: 10 pages, 3 figures

Abstract

The half-life for double-beta decay of Nd-150 has been measured by the NEMO-3 experiment at the Modane Underground Laboratory. Using 924.7 days of data recorded with 36.55 g of Nd-150, we measured the half-life for 2 nu beta beta decay to be T-1/2(2 nu) = (9.11(-0.22)(+0.25)(stat.) +/- 0.63(syst.)) x 10(18) yr. The observed limit on the half-life for neutrinoless double-beta decay is found to be T-1/2(0 nu) > 1.8 x 10(22) yr at 90% confidence level. This translates into a limit on the effective Majorana neutrino mass of < m(nu)> < 4.0-6.3 eV if the nuclear deformation is taken into account. We also set limits on models involving Majoron emission, right-handed currents, and transitions to excited states., We thank the staff at the Modane Underground Laboratory for its technical assistance in running the experiment,Vladimir Tretyak for providing the Monte Carlo event generator, and Wade Fisher for helping with the limit-setting program. We acknowledge support by the grants agencies of the Czech Republic, RFBR (Russia), STFC (UK), and NSF (USA).

Abstract

A new experimental run of searching for EC/EC decay of 106Cd was performed at the Modane underground laboratory (4800 m w.e.) using the TGV-2 spectrometer and ~23.2 g 106Cd with enrichment of 99.57%. The limit on 2νEC/EC decay of 106Cd - T1/2(2νEC/EC) > 3.1×1020 y, at 90% C.L was obtained from the preliminary calculation of experimental data accumulated for 7018 h of measurement. The limits on the resonance neutrino-less double electron capture decay of 106Cd were obtained from the measurement of ~23.2 g of 106Cd with the low-background HPGe spectrometer OBELIX lasted 395 h - T1/2(KL, 2741 keV) > 0.9×1020 y and T1/2(KK, 2718 keV) > 1.4×1020 y at 90% C.L.

Abstract

The collaboration TGV has finished measurement of 2νEC/EC decay of 106Cd with 10 g (Phase I) and 13.6 g (Phase II) samples (with enrichment of 75%), respectively. The times of measurements were 8687h (Phase I) and 12900h (Phase II). The half-life limits (at 90% CL) were obtained for 2νEC/EC decay of 106Cd to the ground state of 106Pd as T1/2>3.0×1020 y (Phase I) and T1/2>4.2×1020 y (Phase II). The collaboration decided to continue with the study of 2νEC/EC decay of 106Cd using 23 g of an isotope enriched to 98.4%. We plan to use the TGV II spectrometer for this measurement and also Si pixel detectors for further study of double beta decay (ββ) processes. [ABSTRACT FROM AUTHOR]

Abstract

The TGV II (Telescope Germanium Vertical) facility is a low background spectrometer operated in Modane Underground Laboratory. It aims at the study of double electron capture of 106Cd. The spectrometer is composed of 32 HPGe planar detectors interleaved with thin-foil samples made of Cd-106 enriched to 75% (total mass about 10 g). In 2006, the main run of phase I (1 year duration) was terminated yielding a new limit on half-life for two-neutrino double electron capture (g.s.→g.s.) in 106Cd as 2.0×1020 years. This limit is significantly higher (by almost three orders of magnitude) than those already published. [ABSTRACT FROM AUTHOR]

Abstract

A search for double electron capture of 106Cd was performed at the Modane Underground Laboratory (4800 m w.e.) using a low-background and high-sensitivity multidetector spectrometer TGV-2 (Telescope Germanium Vertical). New limits on β +/EC, EC/EC decays of 106Cd were obtained from preliminary calculations of experimental data accumulated for 4800 h of measurement of 10 g of 106Cd with enrichment of 75%.

Abstract

New limits on [sup 48]Caβ[sup –] and β[sup –]β[sup –] decays to excited states of [sup 48]Ti have been obtained using a 400cm[sup 3] low-background HPGe detector and an external source of 24.558g enriched CaF[sub 2] powder (9.822g of [sup 48]Ca). The limits for β[sup –] decay to the 6[sup +] ground state and excited 5[sup +] and 4[sup +] states in [sup 48]Sc are 1.6×10[sup 20] yr, 2.5×10[sup 20] yr, and 1.9×10[sup 20] yr at the 90% confidence level. For the β[sup –]β[sup –] decay to [sup 48]Ti, the limits to the first 2[sup +], second 2[sup +], and first 0[sup +] excited states are 1.8×10[sup 20] yr, 1.5×10[sup 20] yr, and 1.5×10[sup 20] yr, again at the 90% confidence level. © 2002 MAIK “Nauka / Interperiodica”.
