We present the first measurement of the coherent dynamic structure factor S(Q,) of solid 3He. At a density of 13.25(10) cm3 mol-1, we observed longitudinal phonons, using high-resolution inelastic x-ray scattering at momentum transfers 6 nm-1 < |Q| <

We have commissioned a new instrument for high resolution inelastic x-ray scattering on the inelastic scattering beamline of the Synchrotron Radiation Instrumentation Collaborative Access Team on sector 3 of the Advanced Photon Source. So far, the in

The high x‐ray flux available at synchrotron radiation sources can cause nonlinearities in photon‐counting detectors unless deadtime corrections are employed. We compute the uncertainties associated with several common deadtime‐correction formu

X-ray synchrotron radiation was used to measure Debye-Waller factors of helium crystals for both ${}^{3}\mathrm{He}$ and ${}^{4}\mathrm{He}$ in both hcp and fcc phases. To our knowledge, there are no previous measurements for ${}^{3}\mathrm{He}.$ The

Thin Ge single crystals (≤1 μm) up to 4 mm in diameter have been fabricated from epitaxial Ge films grown by atmospheric pressure chemical vapor deposition on Si(100) wafers. The thin Ge windows are formed by chemically etching away both the Si su

We present first measurements of the dispersion of excitons in solid helium, taken on a single hcp ${}^{4}\mathrm{He}$ crystal along the $c$ axis. In agreement with studies on helium clusters, the major energy-loss peak can be interpreted as an inter

New data on the phonon dispersion of helium under high pressure was obtained using inelastic x-ray scattering with an energy resolution of several meV. At 9 K and a pressure of 70 MPa a single crystal of hcp4He with a molar volume of 13.3(1) cm3 was
