Neutron stars velocities and magnetic fields

EPJ Web of Conferences, 2018
We study a model that explain neutron stars velocities due to the anisotropic emission of neutrinos. Strong magnetic fields present in neutron stars are the source of the anisotropy in the system.

Thermal effects on nuclear symmetry energy with a momentum-dependent effective interaction

, 2007
The knowledge of the nuclear symmetry energy of hot neutron-rich matter is important for understanding the dynamical evolution of massive stars and the supernova explosion mechanisms. In particular, the electron capture rate on nuclei and/or free protons

Temperature Coefficient of Neutron Multiplication Factor [PDF]

Journal of Nuclear Science and Technology, 1964
A method for calculating the temperature coefficient of the neutron multiplication factor in an infinite homogeneous medium is investigated for the purpose of discussion of the temperature coefficient for thermal reactors. Two kinds of expression for the temperature coefficient of the neutron multiplication factor are derived and given in terms of ...

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.

Intensity of the neutron component of cosmic rays and air humidity

Solar-Terrestrial Physics
Neutron monitor data is currently corrected only for the barometric effect. We cannot, however, exclude that changes in air humidity affect the intensity of the cosmic-ray neutron component recorded by neutron monitors.

Neutron depolarization due to ferromagnetism and spin freezing in CePd_{1−x}Rh_{x}

Physical Review Research, 2022
We report neutron depolarization measurements of the suppression of long-range ferromagnetism and the concomitant emergence of magnetic irreversibilities and spin freezing in CePd_{1−x}Rh_{x} around x^{*}≈0.6.
