Recombination of radiation defects in solid methane - neutron sources and cryo-volcanism on celestial bodies
O. Kirichek, E. V. Savchenko, C. R. Lawson +5
Physicochemical properties of solid methane exposed to ionizing radiation have attracted significant interest in recent years. Here we present new trends in the study of radiation…
Phonon-roton modes of liquid 4He beyond the roton in MCM-41
R. T. Azuah, S. O. Diallo, M. A. Adams +2
We present neutron scattering measurements of the phonon-roton (P-R) mode of superfluid 4He confined in 47 ÅMCM-41 at T = 0.5 K at wave vectors, Q, beyond the roton wave vector (Q_…
High pressure gas vessels for neutron scattering experiments
R. Done, O. Kirichek, B. E. Evans +1
The combination of high pressure techniques with neutron scattering proves to be a powerful tool for studying the phase transitions and physical properties of solids in terms of in…
Neutron Reflection from the Surface of Liquid 4He with and without a Layer of 3He
T. R. Charlton, R. M. Dalgliesh, A. Ganshin +3
We report and discuss the first neutron reflection measurements from the free surface of normal and superfluid 4He and of liquid 3He-4He mixture. In case of liquid 4He the surface…
Search for supersolid 4He in neutron scattering experiments at ISIS
Oleg Kirichek
The observation of a non-classical rotation inertia (NCRI) fraction in bulk solid 4He by M. Chan and E. Kim attracted significant interest as a possible manifestation of supersolid…
Neutron reflection from the surface of normal and superfluid 4He
T. R. Charlton, R. M. Dalgliesh, A. Ganshin +3
The reflection of neutrons from a helium surface has been observed for the first time. The 4He surface is smoother in the superfluid state at 1.54 K than in the case of the normal…
