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.

Imaging solar neutrons below 10 MeV in the inner heliosphere [PDF]
, 2005 Inner heliosphere measurements of the Sun can be conducted with the proposed Solar Sentinel spacecraft and mission. One of the key measurements that can be made inside the orbit of the Earth is that of lower energy neutrons that arise in flares from ...

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.

Neutron dose evaluation in conventional and FLASH proton therapy
Brazilian Journal of Radiation Sciences, 2023 Cancer is the second leading cause of death for children and one of the treatment options for this disease is radiotherapy. Children treated with radiotherapy using photon beams are more likely to develop secondary neoplasms.

An aerogel Cherenkov detector for multi-GeV photon detection with low sensitivity to neutrons [PDF]
, 2014 We describe a novel photon detector which operates under an intense flux of neutrons. It is composed of lead-aerogel sandwich counter modules. Its salient features are high photon detection efficiency and blindness to neutrons. As a result of Monte Carlo
