TRIUMF experiment 497 has measured the parity-violating longitudinal analyzing power Az in p→p elastic scattering at 221.3 MeV incident proton energy. This comprehensive paper includes details of corrections, some magnitude comparable to itself, required arrive final result. The largest correction was for effects first moments transverse polarization. addition result, Az=[0.84±0.29(stat.)±0.17(syst.)]×10−7, parity-violation experimental data base greatly improves constraints on weak...
Abstract BACKGROUND: Rize in Turkey was contaminated by the Chernobyl accident 1986. A comprehensive study planned and carried out to determine radioactivity levels heavy metal concentrations four food categories collected 2008, 2009 2010. RESULTS: Tomato showed highest concentration of 238 U, at 9.43 ± 0.128 Bq kg −1 , whereas lowest 0.20 0.02 measured aubergine samples. The 232 Th 3.22 0.29 grape 40 K found contribute activity all 137 Cs 10.20 4.19 for parsley. average contribution range...
In this paper, we propose a new algorithm based on radial symmetry center method to track colloidal particles close contact, where the optical images of start overlap in digital video microscopy. This overlapping effect is important observe pair interaction potential studies and it appears as additional measurement with conventional tracking analysis. The proposed work simple, fast applicable for not only two but also three more without any modification. uses gradient vectors particle...
When the nucleon component of cosmic ray flux interacts with silicon in computer memory chips, resulting highly ionizing particles can cause errors. Therefore, natural and 27Al( p,α) ( p,3He) total cross sections have been obtained at proton energies 35 45 MeV by integrating differential section angular distributions. The accuracy measurements is significantly better than previous measurements. These measurements, along from literature, show energy dependence Si( section. This was convoluted...
In this paper, we demonstrated that an optical tweezer setup can be calibrated by using a part of the symmetric intensity distribution trapped particle in digital video microscopy. First, modified radial symmetry center method, which was recently proposed position detection algorithm. This algorithm uses gradient vectors distribution, allows us to use calculation center. We applied different camera image configurations, are obtained cutting same experimental frames. further trap stiffness...
Angular distributions of the 3He polarization analysing power were measured for elastic scattering a 33 MeV polarized beam by 4He, 3He, 3H, 2H and 1H targets. The data together with differential cross sections successfully interpreted in terms standard optical model. Two discrete sets parameters found each nucleus. Some features optical-model phase-shifts are discussed compared other results.
A polarized $^{3}\mathrm{He}$ target, which uses conventional optical pumping with $^{4}\mathrm{He}$ discharge lamps, has been used for the measurement of analyzing powers ${A}_{y}$(\ensuremath{\theta}) at energies 25.0, 30.0, 32.5, and 35.0 MeV. The statistical uncertainties in data are on order 0.03; systematic uncertainty is estimated to be 0.05. These compared fits predictions from various phase shift analyses.
Elastic and inelastic scattering of unpolarized polarized protons by $^{40}\mathrm{Ar}$ nuclei for incident energies between 20 50 MeV has been studied reanalyzing experimental spectra the ${2}^{+}$(1.46 MeV) ${3}^{\ensuremath{-}}$(3.68 levels in angular range $30\ifmmode^\circ\else\textdegree\fi{}--160\ifmmode^\circ\else\textdegree\fi{}$ 25.1, 32.5, 40.7 MeV. An isospin dependent soft-rotator coupled-channels optical model with potential containing a dispersive term nonlocal contribution is...
The tracking of micro sized colloidal particles which are optically trapped is an important method to gain information about the pair interaction potential between suspended in a liquid. To track close contact difficult because overlapping particle diffraction patterns causes systematic errors position detection. Recently, template based finding algorithm was reported and verified experimentally. Here, we perform simulations order determine precision that algorithm, as one cannot know real...
In this study, it was determined environmental gamma radiation dose rate for some counties of Trabzon‐Turkey. A detailed ambient measurement has been performed in the seven Trabzon, using a portable survey meter (NaI detector, INSPECTOR 1000). The measurements were indoor and outdoor buildings also at each spot, reading taken 1 m above ground level. rates varied from 42.69 nGy/h 140.91 27.84 121.80 . Average ascertained to be 71.05 60.20 nGy/h, respectively. annual effective doses calculated...
In the present work, radiation doses are estimated from analysis of 40K, 137Cs, 226Ra and 228Ra radionuclides in marine fish Bay Bengal, accumulated ten different human organs: red marrow, lung, thyroid, lower large intestine, upper small breast, stomach, gonads bone surface. The lowest equivalent dose is calculated thyroid as 2.7×10−3 µSv/y highest on surface 1.1×10−1 µSv/y. effective due to (1.2×10−1 µSv/y) whole body, whereas for 40K (3.6×10−2 µSv/y).
