Theoretical analysis of inelastic neutron scattering in solid hydrogen

Theoretical Analysis of Inelastic Neutron Scattering in Solid Hydrogen

The inelastic-neutron-scattering cross section of ( J=1) solid hydrogen is studied and the experimental data of Stein and co-workers analyzed. The rms displacement ⟨u2⟩1/2 is deduced from the data via different methods and mutually consistent values of order 0.65 Å are obtained. The enhancement of the cross section at the libron energy due to libron-phonon interactions is found to be the same, ...

Inelastic neutron scattering of hydrogen trapped in solid argon

2014 Molecular hydrogen was isolated in an argon matrix. Its inelastic neutron scattering functions at momentum transfers of 1 to 7 Å-1 were compared with those of solid hydrogen. Both samples show free rotation without line shift. At high momentum transfer (7 Å-1), the spectrum of pure hydrogen is affected by recoil, whereas no recoil effects could be seen in matrix isolated H,. Revue Phys. Ap...

Inelastic magnetic neutron scattering in CePd3

We have performed time-of-flight neutron scattering measurements on a single crystal of the intermediate valence compound CePd3. At 10K, a Kondo-esque inelastic magnetic scattering peak occurs near DE 1⁄4 60meV with maximum intensity for momentum transfer Q near the ð 2 ; 1 2 ; 0Þ zone boundary. Spectral weight is transferred to lower energy as Q varies until at zone center the intensity at 60m...

Inelastic Neutron Scattering Study of Mn12-Acetate

We report zero-field inelastic neutron scattering experiments on a deuterated powder sample of Mn12-Acetate consisting of a large number of nominally identical spin-10 magnetic clusters. Our resolution enables us to see a series of peaks corresponding to transitions between the anisotropy levels within the spin-10 manifold. A fit to the spin Hamiltonian H = −DS z − μBB · g · S −
