An hybrid Tykhonov method for neutron spectrum unfolding [PDF]

, 2005
An hybrid iterative Tykhonov regularization approach with an accelerating algorithm is considered. This method is illustrated by two neutron spectrum unfoldings measured with a Bonner Sphere system.Comment: 19 pages, work done at ...

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 ...

Accelerator based epithermal neutron source for neutron capture therapy [PDF]

, 1991
Several investigators have suggested that a charged particle accelerator with light element reactions might be able to produce enough epithermal neutrons to be useful in Neutron Capture Therapy. The reaction choice so far has been the Li(p,n) reaction with protons up to 2.5 MeV. A moderator around the target would reduce the faster neutrons down to the

Simulation of the BNCT of Brain Tumors Using MCNP Code: Beam Designing and Dose Evaluation [PDF]

Iranian Journal of Medical Physics, 2012
Introduction BNCT is an effective method to destroy brain tumoral cells while sparing the healthy tissues. The recommended flux for epithermal neutrons is 109 n/cm2s, which has the most effectiveness on deep-seated tumors.

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.

Over‐Water Low‐Energy Neutron Observations for Intensity Corrections Across Cosmic‐Ray Soil Moisture Sensor Networks

Water Resources Research, Volume 61, Issue 9, September 2025.
Abstract Most studies using cosmic‐ray neutron sensors (CRNS) for soil moisture estimation use high‐energy neutron monitor observations to correct for changes in incoming neutron intensity, but there is interest in over‐water CRNS observations and muon observations for such purposes.

Neutron Monitor Based Incoming Flux Correction for Cosmic‐Ray Neutron Sensing of Environmental Water

Water Resources Research, Volume 61, Issue 9, September 2025.
Abstract Monitoring of near‐surface water content with cosmic‐ray neutrons is strongly dependent on heliospheric and geomagnetic conditions. Neutron monitor (NM) stations are commonly used as a reference for the incoming cosmic radiation to correct the hydrological neutron signal.

Structural Architecture of the Cenozoic Kallianos (Post‐?)Orogenic Vein‐Hosted Au‐Ag‐Te Deposit and Its Relationship to the North Cycladic Detachment System, Greece

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract The Kallianos Au‐Ag‐Te deposit is a Cenozoic orogenic‐style deposit on Evia, hosted in the Cycladic Blueschist Unit. Integrated field observations and isotopic data illustrate a connection between the structural architecture that hosts mineralization in the deposit and the regional stress field associated with a crustal‐scale detachment, the ...
