On the spreading layer emission in luminous accreting neutron stars [PDF]

, 2013
Emission of the neutron star surface potentially contains information about its size and thus of vital importance for high energy astrophysics. In spite of the wealth of data on the emission of luminous accreting neutron stars, the emission of their ...

Radiation of Neutron Stars Produced by Superfluid Core [PDF]

, 2002
We find that neutron star interior is transparent for collisionless electron sound, the same way as it is transparent for neutrinos. In the presence of magnetic field the electron sound is coupled with electromagnetic radiation and form the fast ...

Development of a powerful UCN source at PNPI's WWR-M reactor [PDF]

EPJ Web of Conferences, 2019
The WWR-M reactor at PNPI is planned to be equipped with a high-flux source for ultracold neutrons (UCNs). The method of UCN production is based on neutron conversion in superfluid helium, exploiting the particular qualities of that quantum liquid.

Research on Neutronics Safety Parameters of the AP1000 Nuclear Reactor under Different Conditions

Energies, 2023
Changes in temperature during reactor operation may cause changes in physical parameters, leading to core overheating and accidents. It is essential to analyze and assess the safety parameters of the core under different operating conditions.

Dynamic rotor mode in antiferromagnetic nanoparticles [PDF]

, 2015
We present experimental, numerical, and theoretical evidence for a new mode of antiferromagnetic dynamics in nanoparticles. Elastic neutron scattering experiments on 8 nm particles of hematite display a loss of diffraction intensity with temperature, the
