Scientists at the National Institute of Standards and Technology (NIST) with colleagues elsewhere have employed neutron imaging and a reconstruction algorithm
Max Planck, one of the Twentieth Century’s most eminent physicists, observed, "An experiment is a question that science poses to Nature, and a measurement is
Each year, hundreds of meteorites — rocky bodies left over from the formation of the solar system — bombard Earth, delivering minerals, metals and water to our
The Department of Homeland Security/Domestic Nuclear Detection Office (DHS/DNDO) is pursuing a course to transform 3 He alternative technologies into integrated
The Neutron Spin Rotation (NSR) collaboration has developed a neutron spin polarimeter that has allowed the precise measurement of spin rotations at a level of
Neutron beta-decay is typically considered as a three-body process, but it is always accompanied by inner-bremsstrahlung soft photons, n → e − + p + ν e + γ
We continue to work improving techniques in fast neutron detection using segmented spectrometers based on the principle of capture-gating. Our approach employs

To test the bound-state quantum electrodynamics (BSQED), we have performed high precision x- ray spectroscopy of the 5g→4f and 5f→4d transitions (BSQED
Positron annihilation lifetime spectroscopy uses positrons to probe material defects/voids/free volume at the sub-nm scale. The general working principle is
Light elements such as helium, lithium, boron, and nitrogen are essential constituents in materials that enable energy technologies; lithium ion batteries
