Search for anomalous scattering of keV neutrons from H2O-D2O mixtures.

چکیده
We measured the neutron scattering intensities from pure liquid H2O relative to that of pure D2O and also relative to H2O-D2O mixtures, at room temperature. This study is relevant to the problem of quantum entanglement. The neutrons were generated from an electron Linac and the final energy of the scattered neutrons was fixed at 24.3 keV using a 20 cm thick pure iron filter. The scattering intensity ratios were found to agree with expected values deduced from the tabulated total cross sections within an accuracy of 3%. Thus no anomaly was observed.

Anomalies in H2O-D2O Mixtures: Evidence for the Two-Fluid Structure of Water
Recent probing of H2O-D2O mixtures by various means (neutron deep inelastic scattering, Raman absorption, electrical H/D conductivity) revealed an unexpected dependence of the relevant physical quantities on the isotopic composition of the mixture. We show that these observations can find their physical rationale in the context of an approach to the physics of liquid water which takes into acco...
متن کاملLow-angle neutron scattering from chromatin subunit particles.
Monomer chromatin particles containing 140 base pairs of DNA and eight histone molecules have been studied by neutron scattering. From measurements in various H2O/D2O mixtures, radii of gyration and the average scattering density of the particle were determined. The radius of gyration under conditions when scattering from the DNA dominates is 50A, and when scattering from the protein dominates,...
متن کاملAnomalous Diffusion of Adsorbed Water A Neutron Scattering Study of Hydrated Myoglobin
The neutron scattering spectrum of bound H2O was determined from the excess scattering of H2O-hydrated myoglobin relative to a sample hydrated with D2O. The resulting vibrational difference spectrum shows the well known translational and librational bands of bulk water. Significant discrepancies arise at low frequencies indicating that the diffusive motion is strongly retarded by interactions w...
متن کاملCorrelation of excess power and helium production during D2O and H2O electrolysis using palladium cathodes
A critical issue in determining whether or not the anomalous effects that occur during D2O electrolysis are of nuclear origin is the measurement of nuclear products in amounts sufficient to explain the rate of excess enthalpy generation. Calorimetric evidence of excess power up to 27% was measured during the electrolysis of heavy water using palladium cathodes. Maximum excess power was 0.52 W (...

The Gaerttner LINAC Center at RPI uses a 60 MeV electron linear accelerator to produce short pulses of neutrons with duration of 5-5000 ns. The main research thrust at the Center is nuclear data for nuclear reactors and criticality safety applications. The Center includes several setups for time-of-flight measurements including neutron transmission, capture and scattering detectors, and a lead ...
