Experimental study of ultracold neutron production in pressurized superfluid helium
P. Schmidt-Wellenburg, J. Bossy, E. Farhi +5
We have investigated experimentally the pressure dependence of the production of ultracold neutrons (UCN) in superfluid helium in the range from saturated vapor pressure to 20bar.…
Velocity autocorrelation in liquid para-hydrogen by quantum simulations for first-principle computations of the neutron cross sections
E. Guarini, M. Neumann, U. Bafile +4
Accurate knowledge of the single-molecule (self) translational dynamics of liquid para-H2 is an essential requirement for the calculation of the neutron scattering properties of th…
Structure and dynamics of l-Ge: Neutron scattering experiments and ab initio molecular dynamics simulations
Virginie Hugouvieux, Emmanuel Farhi, Mark R. Johnson +3
We report the first measurements of the dynamics of liquid germanium (l-Ge) by quasi-elastic neutron scattering on time-of-flight and triple-axis spectrometers. These results are c…
New excitations in bcc He - an inelastic neutron scattering study
O. Pelleg, J. Bossy, E. Farhi +3
We report neutron scattering measurements on bcc solid % He. We studied the phonon branches and the recently discovered ''optic-like'' branch along the main crystalline direc…
Observation of Macroscopic Structural Fluctuations in bcc Solid 4He
O. Pelleg, M. Shay, S. G. Lipson +6
We report neutron diffraction studies of low density bcc and hcp solid 4He. In the bcc phase, we observed a continuous dynamical behaviour involving macroscopic structural changes…
Observation of a new excitation in bcc solid 4He by inelastic neutron scattering
T. Markovich, E. Polturak, J. Bossy +1
We report neutron scattering measurements of the phonons in bcc solid 4He. In general, only 3 accoustic phonon branches should exist in a monoatomic cubic crystal. In addition to t…
