Neutron drip transition in accreting and nonaccreting neutron star crusts
, 2015 The neutron-drip transition in the dense matter constituting the interior of neutron stars generally refers to the appearance of unbound neutrons as the matter density reaches some threshold density $\rho_\textrm{drip}$.

Advanced Functional Materials, EarlyView.This study demonstrates coherent control of 15N nuclear spins coupled to VB−${\text{V}}_{\text{B}}^{-}$ centers in isotope‐enriched hexagonal boron nitride. Selective addressing via spin‐state mixing enables Rabi driving, quantum gates, and coherence times exceeding 10 μs$\umu{\rm s}$.

Effective Thermal Properties of a HTS Transition Edge Bolometer for High‐Flux Neutron Detection
Advanced Electronic MaterialsMany applications require monitoring of increasingly high neutron flux levels. Pre‐neutron characterization is performed of a superconducting transition edge bolometric device, sensitive to neutrons by an enriched boron carbide (10B4C) layer.

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1949 The problem of neutron diffraction by crystals is treated by analogy with X-ray diffraction, consideration being given to the perfect crystal, the mosaic crystal and the powdered block. The first part of the paper deals with a comparison between X-ray and neutron diffraction and it is shown that quantitatively the two are similar, apart ...

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation
Advanced Functional Materials, EarlyView.This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Neutron Shielding Optimization Studies [PDF]
, 2015 The IsoDAR sterile-neutrino search calls for a high neutron flux from a 60 MeV proton beam striking a beryllium target, that flood a sleeve of highly-enriched 7Li, the beta-decay of the resulting 8Li giving the desired neutrinos for the veryshort ...

Advanced Functional Materials, EarlyView.Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Quantum Beam ScienceThis study developed a neutron-beam-focusing supermirror for grazing-incidence small-angle neutron scattering (GISANS) measurements. We adopted point-to-point beam focusing based on an ellipse whose two foci correspond to a virtual point source and a ...

Estimation of scattering contribution in the calibration of neutron devices with radionuclide sources in rooms of different sizes [PDF]
Nuclear Technology and Radiation Protection, 2015 Calibrations of neutron devices used in area monitoring are often performed by radionuclide neutron sources. Device readings increase due to neutrons scattered by the surroundings and the air.
