Phonon dynamics in SrFe2As2 and SrFeAsF parent pnictide compounds: How different/similar when compared to Ca- and Ba-compounds?
R. Mittal M. Zbiri, S. Rols, Y. Su +9
We report detailed measurements of temperature dependence and ab initio lattice dynamical calculations of the phonon density-of-states of two Sr based iron pnictide parent compound…
Production of Ultra-Cold-Neutrons in Solid α-Oxygen
E. Gutsmiedl, A. Frei, F. Boehle +4
Our recent neutron scattering measurements of phonons and magnons in solid α-oxygen have led us to a new understanding of the production mechanismen of ultra-cold-neutrons (UCN) in…
New Understanding of Ultra-Cold Neutron Production in Solid Deuterium
A. Frei, E. Gutsmiedl, C. Morkel +5
Our recent neutron scattering measurements of phonons and other quasi-particle excitations in solid deuterium (sD) and the extraction of the density of states for phonons and r…
Density of states in solid deuterium: Inelastic neutron scattering study
A. Frei, E. Gutsmiedl, C. Morkel +6
The dynamics of solid deuterium (sD2) is studied by means of inelastic scattering (coherent and incoherent) of thermal and cold neutrons at different temperatures and para-ortho ra…
Dynamic Disorder in Negative Thermal Expansion Compound Zn(CN)2
R. Mittal, S. Mitra, H. Schober +2
Dynamical disorder in negative thermal expansion compound Zn(CN)2 is investigated by quasielastic neutron scattering technique in the temperature range 170-320 K. Significant quasi…
