For their appropriate temporal resolution, scintillator detectors are used in the Alborz observatory. In this work, the behavior of the scintillation detectors for the passage of electrons with different energies and directions were studied using the simulation code GEANT4. Pulse shapes of scintillation light, and such characteristics as the total number of photons, the rise time and the fallin...
In this paper, experiences of the last 20 years with PERALS-technique are described. PERALS stands for photo electron-rejecting alpha liquid scintillation. This scintillation technique was developed by Jack McDowell in 1970s and is a powerful analyses many natural nuclides also beta nuclide 90Sr. The principle based on selective extraction radionuclide from water phase means complexing or ion p...
The aim of this study is to evaluate quantitatively the effectiveness ion exchange resins and activated carbon in tritium measurement. A standard water sample was adjusted a concentration 5 Bq L−1. This stirred with cation (PCH) anion (PAO) carbon. After stirring samples, supernatant each filtered through 0.45 µm membrane filters. electrical conductivity an experimental condition, where amounts...
The s and t dependence of incoherent +(3100) photoproduction from deuterium has been measured at the Stanford Linear Accelerator Center. $(3'700) photoproduction and #(3100) photoproduction from hydrogen have also been measured,Two narrow resonances have recently been discovered, the $(3100) and the zjJ(3700). l Since the original discovery, the $(3100) has been observed in photo-production by ...
