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.

Influence of Mars Topography on Neutral Surface Radiation: Modeling and MSL/RAD Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Since landing in 2012, the Radiation Assessment Detector (RAD) onboard the Mars science laboratory (MSL) Curiosity rover has encountered different local landscapes, which have induced variations in the local surface environment. The aim of this study is to include realistic and site‐specific local topography for any position in a radiation ...

Porphyry and Epithermal Au-Cu Systems of the Southern Caucasus and Northern Iran

Bulletin of the Mineral Research and Exploration
This article presents tangible geological evidence for coexistence of porphyry copper and epithermal gold systems within single polygenic deposits and provides a paleothermophysical model for their origins.

The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs), resulting in significantly higher radiation levels and enhanced health risks.

Parity Nonconservation in 106Pd and 108Pd Neutron Resonances

, 1999
Parity nonconservation (PNC) has been studied in the neutron p-wave resonances of 106Pd and 108Pd in the energy range of 20 to 2000 eV. Longitudinal asymmetries in p-wave capture cross sections are measured using longitudinally polarized neutrons ...

Irrigation Monitoring With Cosmic‐Ray Neutron Sensors: Unraveling Field Experiments With Neutron Transport Simulations

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Irrigation is essential for stabilizing yields and sustaining food production, yet it faces increasing challenges, especially in water‐scarce regions. Cosmic‐ray neutron sensors (CRNS) are a promising tool in irrigation management as they can continuously monitor soil water content (SWC) over large areas.

Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

Advanced Functional Materials, Volume 36, Issue 3, 8 January 2026.
Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.

Low-sulfidation epithermal Au mineralization in the Tikmehdash 2 deposit (southeast of Bostan Abad): Constraints on geology, mineralization, geochemistry, and fluid inclusions

Journal of Economic Geology
Tikmehdash 2 gold (Au) deposit is part of the Miyaneh-Bostan Abad metallogenic subzone. Au mineralization occurs in Mn- and Au-bearing quartz veins hosted by Eocene and Miocene volcanic-sedimentary sequences.

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 ...
