To obtain high quality of results in gamma spectrometry, it is necessary to calibrate energy and efficiency of gamma detector as accurate as possible. To achieve this aim, utilizing the convenient gamma source can be very useful. Therefore, purpose of present study was to evaluate the determined efficiency by single point gamma sources and multi-nuclides gamma source in a high purity germanium ...
introduction: the mechanism of action and metabolism of clozapine, a complex drug used in psychopharmacology, is not completely understood. the effects of this compound in human body are related to some interactions with serotonin and dopamine neurotransmitter receptors. to further elucidate the mechanism of action and to support ongoing drug metabolism studies, [14c] clozapine with suitable ra...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Recent results of research passive and active optical waveguides made high-purity chalcogenide glasses for middle infrared fiberoptic evanescent wave spectroscopy liquid gaseous substances are presented. On the basis selenide telluride glass fibers, novel types highly sensitive fiber probes developed. Pr(3+)- Tb(3+)-doped Ga(In)-Ge-As-Se Ga-Ge-Sb-Se 4.2–6 μm wavelength radiation sources created...
The KM3NeT Collaboration is constructing two deep-sea Cherenkov detectors in the Mediterranean Sea. ARCA detector aims at TeV-PeV neutrino astronomy, while ORCA optimised for atmospheric oscillation studies energies of a few GeV. In this contribution, an analysis data collected with first deployed detection units presented. A high-purity sample neutrinos selected demonstrating capability detect...
The lifetimes of B + and B 0 mesons have been measured using a sample of 400,000 hadronic Z 0 decays collected by the SLD experiment at the SLC between 1993 and 1998. This inclusive topological measurement includes 250,000 hadronic Z 0 decays collected since 1996 with the SLD upgrade vertex detector. A high statistics sample of 30028 19636 charged neutral vertices with good charge purity is obt...
Although designed primarily as a hard X-ray imager and spectrometer, the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) is also capable of measuring the polarization of hard X-rays (20–100 keV) from solar flares. This capability arises from the inclusion of a small unobstructed Be scattering element that is strategically located within the cryostat that houses the array of nine germaniu...
Reaction mechanism analyses performed with a 4pi detector for the systems 208Pb + Ge, 238U + Ni and 238U + Ge, combined with analyses of the associated reaction time distributions, provide us with evidence for nuclei with Z=120 and 124 living longer than 10(-18) s and arising from highly excited compound nuclei. By contrast, the neutron deficient nuclei with Z=114 possibly formed in 208Pb + Ge ...
A surface-illuminated photoconductive detector based on Ge0.91Sn0.09 quantum wells with Ge barriers grown on a silicon substrate is demonstrated. Photodetection up to 2.2µm is achieved with a responsivity of 0.1 A/W for 5V bias. The spectral absorption characteristics are analyzed as a function of the GeSn/Ge heterostructure parameters. This work demonstrates that GeSn/Ge heterostructures can b...
