The periodic time modulations, found recently in the two-body orbital electron-capture (EC) decay of both, hydrogen-like $^{140}$Pr$^{58+}$ and $^{142}$Pm$^{60+}$ ions, with periods near to 7s amplitudes about 20%, were re-investigated for case by using a 245 MHz resonator cavity much improved sensitivity resolution. We observed that exponential EC is modulated period $T = 7.11(11)$s, accordance modulation 7.12(11)$ s as obtained from simultaneous observations capacitive pick-up, employed...
The Large Area Picosecond PhotoDetector (LAPPD) Collaboration was formed in 2009 to develop large-area photodetectors capable of time resolutions measured pico-seconds, with accompanying sub-millimeter spatial resolution. During the next three and one-half years developed LAPPD design 20 x cm modules gains greater than $10^7$ non-uniformity less $15\%$, resolution 50 psec for single photons 700~microns both lateral dimensions. We describe R\&D performed micro-channel plate glass...
This review treats the process of dissociative recombination molecular ions with electrons and its role in shaping properties a weakly-ionized plasma inert gases mixtures them. Data are presented on rate constants efficiency formation excited atoms various states. We discuss experimental methods that enable study processes over wide range variation electron temperature. analyze competition alternative mechanisms recombinatively nonequilibrium plasmas, manifestation heteronuclear kinetics...
The Aragats Space Environment Center in Armenia provides real-time monitoring of cosmic particle fluxes. Neutron monitors operating at altitudes 2000 m and 3200 on Mt continuously gather data to detect possible abrupt enhancement the count rates. Additional high precision detectors, measuring muon electron fluxes, along with directional information have been put operation summer 2002. We plan use this establish an early warning system against extreme solar energetic (SEP) events which pose...
We report the measurements of pseudodielectric function, far-infrared reflectivity, and Raman scattering spectra in ${\mathrm{Sr}}_{14}{\mathrm{Cu}}_{24}{\mathrm{O}}_{41}$ single crystal. study lattice spin dynamics ${\mathrm{Cu}}_{2}{\mathrm{O}}_{3}$ ladders ${\mathrm{CuO}}_{2}$ chains this compound. The ellipsometric optical reflectivity yield gap values 1.4, 1.86, 2.34 eV (2.5 eV) for (chains) along c axis 2.4 a axis. electronic structure is analyzed using tight-binding approach...
Abstract Thin films of lead tin sulphide PbSnS 2 were deposited on glass substrates at 100 °C vacuum pressure 3×10 –6 mbar using a thermal evaporation method. Scanning electron microscopy (SEM) and X‐ray characterization revealed that thin monophase polycrystalline. The average particle size was approximately 28 nm. Absorption coefficient (∼10 5 cm –1 ) found from transmission optical spectroscopy measurements. Its fundamental absorption edge is shown to be 1.65 eV with direct allowed...
For the ${\ensuremath{\beta}}^{\ensuremath{-}}$-decay of neutron we analyze continuum-state and bound-state decay modes. We calculate rates, electron energy spectrum for mode, angular distributions probabilities The theoretical results are obtained new value axial coupling constant ${g}_{A}=1.2750(9)$, recently by H. Abele [Prog. Part. Nucl. Phys. 60, 1 (2008)] from fit experimental data on coefficient correlation spin momentum mode. take into account contribution radiative corrections...
