It is generally recognized that cat skin is an important extrasalivary source of the major cat allergen, Fel d I. Nevertheless, since cat saliva is readily applied to the skin during grooming, we tried to demonstrate that Fel d I can accumulate on ca

The feasibility of using a hybrid detection system, consisting of multiple narrow bismuth germanate (BGO) crystals coupled to one photomultiplier for coincidence timing, and individual mercuric iodide (HgI2) photodetectors coupled to each BGO crystal

Highly perfect n-type CdTe single crystals grown by the sealed-ingot-zone refining method have been used to fabricate semiconductor surface-barrier detectors for X- and low-energ, γ-ray analysis. An energy resolution of 2.0 keV /fwhm/ and 1.5 keV /f

Cadmium telluride detectors were fabricated from low resistivity (50–500 Ω·cm) n-type crystals grown by the sealed-ingot-zone refining method. Physical parameters of this kind of detector were discussed and the factors influencing them were analy
