  • Experiments with ultracold neutrons 
    Nesvizhevsky, V.V. (Физика низких температур, 2011)
    Ultracold neutrons (UCN) form a tiny low-energy fraction in Maxwelian spectrum of thermal neutrons in moderators of nuclear reactors and spallation sources. Their energy is extremely small (~10⁻⁷ eV), their velocity is a ...
  • Infrared light interaction with impurity gels in superfluid helium 
    Izotov, A.N.; Efimov, V.B. (Физика низких температур, 2011)
    The quick cooling of impurity–helium mixture into superfluid helium formats a distinctive soft matter — impurity–helium gel, clusters of which conglutinate into nanoparticles. The sizes of the particles and its mutual ...
