Image-forming focusing mirrors were employed to demonstrate their applicability to two different modalities of neutron imaging, phase imaging with a far-field interferometer, and magnetic-field imaging through the manipulation of the neutron beam pol

We experimentally demonstrate that electrically neutral particles, neutrons, can be used to directly visualize the electrostatic field inside a target volume that can be isolated or occupied. Electric-field images were obtained using a polychromatic,

The aCORN experiment measures the neutron decay electron-antineutrino correlation ($a$-coefficient) using a novel method based on an asymmetry in proton time-of-flight for events where the beta electron and recoil proton are detected in delayed coinc

The presence of a Higgs amplitude mode is revealed in a two-dimensional spin-half quantum antiferromagnet, C9H18N2CuBr4 by means of neutron scattering. Spontaneous symmetry-breaking quantum phase transitions play an essential role in condensed-matter

As a neutron scatters from a target nucleus, there is a small but measurable effect caused by the interaction of the neutron’s magnetic dipole moment with that of the partially screened electric field of the nucleus. This spin-orbit interaction is

The neutron polarization of the NG-C beamline at the NIST Center for Neutron Research was measured as part of the aCORN neutron beta decay experiment. Neutron transmission through a polarized 3He spin filter cell was recorded while adiabatic fast pas

An important consideration when designing a magnetostatic cavities for various applications is to maximize the ratio of the volume of field homogeneity to overall size of the solenoid. We report a design of a magnetically shielded solenoid that signi

We report an experimental implementation for neutron transverse polarization analysis that is capable of detecting a small angular change (≪10−3 rad) in neutron spin orientation. This approach is demonstrated for monochromatic beams, and we show

This article reviews the physics and technology of producing large quantities of highly spin-polarized 3He nuclei using spin-exchange (SEOP) and metastability-exchange (MEOP) optical pumping. Both technical developments and deeper understanding of th
