Determination of neutron temperature in irradiation channels of reactor [PDF]
Journal of Radioanalytical and Nuclear Chemistry, 2010 The neutron temperature is a characteristic parameter in irradiation channels of reactor. For nuclides which have resonances in the thermal neutron energy range, their Westcott g-factors are different from unity. The values of g-factors and cross-sections of (n, γ) reaction of these nuclides are temperature dependence.

Emission of neutrino-antineutrino pairs by hadronic bremsstrahlung processes
EPJ Web of Conferences, 2016 We review our recent calculations of neutrino-antineutrino pair production from bremsstrahlung processes in hadronic collisions at temperature and densities relevant for core-collapse supernovae. We focus on neutron-neutron and neutron-α collisions.

Determining the relaxation time from a temperature-dependent scan of the neutron spin-echo signal amplitude [PDF]
EPJ Web of Conferences, 2022 Temperature-dependent scans of the neutron scattering intensity are commonly employed in high energy-resolution quasielastic measurements. Besides serving as a useful diagnostic tool for identifying the temperature range that could give rise to a ...

Cooling of neutron stars with quark-hadron continuity [PDF]
EPJ Web of Conferences, 2022 Neutron stars are high-density objects formed by the gravitational collapse of massive stars, and the whole star can be likened to a giant nucleus. The interior of a neutron star is considered to contain exotic particles and states which do not appear in
