Neutron Reflection from the Surfaces of Liquid
We report and discuss the first neutron reflection measurements from the free surfaces of normal and superfluid He and of a liquid He-He mixture. In case of liquid He the surface roughness is different above and below the lambda transition, being smoother in the superfluid state. For the superfluid, we also observe the formation of a surface layer ∼ 200 Å thick which has a subtly different neut...
متن کاملAccurate characteristics of Helium in nano-channels
This article describes an accurate subPico flowmeter bifurcatedin to liquid and gas flowrates less than 1mol/s for both MEMS/NEMS and cryogenic technology applications. The MEMS/NEMS are described as either two Gauges (instrument), or quartz fluctuating forks, even if the liquid or gas flows through an element, as well as cryogenic technology consisting of arrays of e...

متن کاملBroadband X - ray emission and the reality of the broad iron line from the Neutron Star – White Dwarf X - ray binary 4 U 1820 – 30
Broad relativistic iron lines from neutron star X-ray binaries are important probes of the inner accretion disk. The X-ray reflection features can be weakened due to strong magnetic fields or very low iron abundances such as is possible in X-ray binaries with low mass, first generation stars as companions. Here we investigate the reality of the broad iron line detected earlier from the neutron ...
متن کاملA note on the ultracold neutron production by neutron deceleration on clusters in liquid helium
An evaluation of slow neutron deceleration through their interaction with nanoclusters in liquid helium is performed. It is shown that this process is strongly suppressed if clusters are bound by the van der Waals interaction. PACS: 28.20.-v; 25.40.Fq; 36.40.C; 63.22.Kn
