Natural fractionation of 238 U / 235 U
The isotopic composition of U in nature is generally assumed to be invariant. Here, we report variations of the U/U isotope ratio in natural samples (basalts, granites, seawater, corals, black shales, suboxic sediments, ferromanganese crusts/ nodules and BIFs) of 1.3‰, exceeding by far the analytical precision of our method ( 0.06‰, 2SD). U isotopes were analyzed with MC-ICP-MS using a mixed U–...
متن کاملPhoton emission intensities in the decay of U-235.
New measurements of photon emission intensities in the decay of U-235 were performed. Source was prepared by deposition of a U-235 solution on glass plate. Standardization was carried out by defined solid angle alpha counting, giving the reference activity with 0.7% relative combined uncertainty. Gamma spectrometry was performed with accurately calibrated high-purity germanium detectors. Correc...
متن کاملRelative 235 U ( n , γ ) and ( n , f ) cross sections from 235 U ( d , p γ ) and ( d , pf )
Relative 235 U(n,γ) and (n,f) cross sections from 235 U(d,pγ) and (d,pf) The internal surrogate ratio method allows for the determination of an unknown cross section, such as (n,γ), relative to a better-known cross section, such as (n,f), by measuring the relative exit-channel probabilities of a surrogate reaction that proceeds through the same compound nucleus. The validity of the internal sur...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولA Spectrochemical Determination of Sodium in Blood Serum*
A spectrochemical method for the quantitative analysis of sodium in blood serum has been worked out and used during the past 2 years for routine analyses. It differs in several respects from the methods described by Thomson and Lee (l), Langstroth (2), and Duffendack et al. (3) for measuring sodium in body fluids. The first two require specially constructed sparking arrangements for exciting th...
