Neutron reflection from surface-induced nana-stratified He-3/He-4 mixtures
It is proposed to use neutron reflectometry to study surface-induced nano-stratification of 3He-4He mixtures in the ultra-low temperature limit. The experiment promises to... -
Neutron reflection from the surface of a liquid 3He-4He mixture
In our previous experiments we have investigated the surface properties of liquid 3He - 4He mixtures by neutron reflection. We have shown that in broad temperature range there... -
Investigation of the relevant thermodynamic parameters for the production of ...
With fantastic flux gains over its liquid conterpart, a solid methane moderator is essential to the newly built Second Target Station at ISIS. Unfortunately, it is notoriously... -
Neutorn Reflection from a 3He layer adsorbed onto liquid 4He
More than four decades ago A. F. Andreev predicted theoretically the existence of quantum statesof 3He atoms on free surface of liquid 4He . In other words, at low temperatures,... -
The use of neutron diffraction to determine residual stresses in standard ISI...
High-pressure research is one of the fastest-growing areas of natural science. The European Commission is funding the Sample Environment Joint Research Activity (JRA) between... -
Using small angle neutron diffraction to describe the status of water in solu...
Fish oocytes and embryos are complex cryobiological objects for which, successful cryopreservation has still not been achieved. This circumstance seriously restricts the... -
Low energy excitations in solid 4He
The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the... -
Well, well, well: the free energy landscape of hydrogenated La(Fe,Si)13?
Magnetic cooling promises efficiency savings at room temperature but requires rapid cycling of a magnetic refrigerant in a magnetic field. Refrigerants with first order... -
Investigation of SANS in the region of superfluid transition
We propose SANS measurements of 4He in a region of supefluid transition (2.2 K). The main aim of the experiment is to see whether at small-angle scattering there is an... -
Neutron reflectometry study of liquid helium surface
In our recent experiment RB1120146 we have obtained new exciting results on neutron scattering on liquid He surface. At 1.5 and 2.3K there was no difference in reflectivity... -
Bose-Einstein Condensation in solid helium confined in porous media
We propose measurements of the Bose-Einstein Condensate (BEC) fraction n0 of solid helium confined in porous media. A superfluid fraction in solid helium in Vycor, in aerogel... -
Neutron critical opalescence near the critical points of 3He and 3He-4He mixt...
Building on our preliminary neutron transmission results from the CRISP instrument (see below), we propose to undertake a detailed study of critical fluctuations in 3He near its...
