Neutron lifetime puzzle and neutron–mirror neutron oscillation [PDF]
The European Physical Journal C, 2019 The discrepancy between the neutron lifetimes measured in the beam and trap experiments can be explained via the neutron $n$ conversion into mirror neutron $n'$, its dark partner from parallel mirror sector, provided that $n$ and $n'$ have a tiny mass splitting order $10^{-7}$ eV.

Characterization and use of Stilbene scintillator for neutron metrology and spectrometry from 100 keV to 22 MeV [PDF]
EPJ Web of Conferences, 2023 Stilbene scintillators have now the capability to extend the neutron energy measurement from 100 keV to 1 MeV. To be used as spectrometers, scintillators have to be characterized in entire energy range covered.

Phonons and Thermal Expansion Behavior of NiSi and NiGe
Frontiers in Chemistry, 2018 We have carried out first principles calculations of the vibrational and thermodynamic behavior in NiSi and isostructural compound NiGe. Phonon density of states has also been measured in NiSi using inelastic neutron scattering techniques.

Neutron skins and neutron stars [PDF]
AIP Conference Proceedings, 2013 The neutron-skin thickness of heavy nuclei provides a fundamental link to the equation of state of neutron-rich matter, and hence to the properties of neutron stars. The Lead Radius Experiment ("PREX") at Jefferson Laboratory has recently provided the first model-independence evidence on the existence of a neutron-rich skin in 208Pb.

Neutron features at the UPM neutronics hall [PDF]
Applied Radiation and Isotopes, 2012 The neutronics hall of the Nuclear Engineering Department at the Polytechnical University of Madrid has been characterized. The neutron spectra and the ambient dose equivalent produced by an (241)AmBe source were measured at various source-to-detector distances on the new bench.

Comparison of neutron/gamma separation qualities of various organic scintillation materials [PDF]
EPJ Web of Conferences, 2020 In this work we compare the pulse-shape discrimination (PSD) properties of EJ-299-33A, BC-501A, stilbene, p-terphenyl and Hidex Aqualight in neutron field generated by the LVR-15 reactor with silicon filter utilization.

Bouncing neutrons and the neutron centrifuge [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2003 The recent observation of the quantum state of the neutron bouncing freely under gravity allows some novel experiments. A method of purifying the ground state is given, and possible applications to the measurement of the electric dipole moment of the neutron and the short distance behaviour of gravity are discussed.

Soil Moisture and Air Humidity Dependence of the Above-Ground Cosmic-Ray Neutron Intensity
Frontiers in Water, 2021 Investigations of neutron transport through air and soil by Monte Carlo simulations led to major advancements toward a precise interpretation of measurements; they particularly improved the understanding of the cosmic-ray neutron footprint.
