Fine Structure Discussion of Parity-Nonconserving Neutron Scattering at Epithermal Energies

, 1994
The large magnitude and the sign correlation effect in the parity non-conserving resonant scattering of epithermal neutrons from $^{232}$Th is discussed in terms of a non-collective $2p-1h$ local doorway model.

Holocene Glacial–Paraglacial–Periglacial Transitions of a Sub‐Arctic Glacial Cirque, Fremri‐Grasárdalur, Northern Iceland

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 78-106, January/March 2026.
ABSTRACT The aim of this work is to study a variety of glacial, periglacial and paraglacial features found in a small cirque, Fremri‐Grasárdalur, in Tröllaskagi (Northern Iceland). We implement a multidisciplinary approach combining high‐resolution geomorphological mapping, horizontal/vertical boulder displacement (from 1994 to 2019) and surface ...

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

Advanced Functional Materials, Volume 35, Issue 52, December 23, 2025.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

Buoy‐Based Detection of Low‐Energy Cosmic‐Ray Neutrons to Monitor the Influence of Atmospheric, Geomagnetic, and Heliospheric Effects

Earth and Space Science
Cosmic radiation on Earth responds to heliospheric, geomagnetic, atmospheric, and lithospheric changes. In order to use its signal for soil hydrological monitoring, the signal of thermal and epithermal neutron detectors needs to be corrected for external

Predicting a Gapless Spin-1 Neutral Collective Mode branch for Graphite

, 2001
Using the standard tight binding model of 2d graphite with short range electron repulsion, we find a gapless spin-1, neutral collective mode branch {\em below the particle-hole continuum} with energy vanishing linearly with momenta at the $\Gamma$ and $K$

Development of a Time-Gated Epithermal Neutron Spectrometer for Resonance Absorption Measurements Driven by a High-Intensity Laser

Quantum Beam Science
The advance of laser-driven neutron sources (LDNSs) has enabled neutron resonance spectroscopy to be performed with a single shot of a laser. In this study, we describe a detection system of epithermal (∼eV) neutrons especially designed for neutron ...

A Microscopic T-Violating Optical Potential: Implications for Neutron-Transmission Experiments

, 1994
We derive a T-violating P-conserving optical potential for neutron-nucleus scattering, starting from a uniquely determined two-body $\rho$-exchange interaction with the same symmetry.
