Spin Susceptibility of Neutron Matter at Zero Temperature [PDF]

Physical Review Letters, 2001
The Auxiliary Field Diffusion Monte Carlo method is applied to compute the spin susceptibility and the compressibility of neutron matter at zero temperature. Results are given for realistic interactions which include both a two-body potential of the Argonne type and the Urbana IX three-body potential.

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.
