High energy neutron scattering from hydrogen using a direct geometry spectrometer (2009)
Stock, C., Cowley, R. A., Taylor, J. W., Bennington, S. M.
Deep inelastic neutron scattering experiments using indirect time-of-flight spectrometers have reported a smaller cross section for the hydrogen atom than expected from conventional scattering...
Gehring, P. M., Hiraka, H., Stock, C., Chen, W., ...
We have used neutron scattering techniques to characterize the diffuse scattering and lattice dynamics in single crystals of the relaxor PMN from 10K to 900K. We observed two distinct types of...

Wen, JS, Xu, GY, Stock, C, Gehring, PM, Zhong, Z, Boatner, LA, ...
We present high-energy x-ray (67 keV) and neutron-scattering measurements on a single crystal of K1-xLixTaO3 for which the Li content (x=0.02) is less than x(c)=0.022, the critical value below which...

Single crystal growth of YbRh2Si2 using Zn flux (2007)
Hu, RW, Hudis, J, Stock, C, Broholm, CL, Petrovic, C
Large single crystals of YbRh2Si2 have been successfully grown from a high-temperature solution technique, using Zn flux and followed by a decanting process. As opposed from the crystals growth from...

Objective: 17β-estradiol is known to delay the onset of atherosclerosis in women but cellular mechanisms are still unclear. Estrogens bind to specific receptors and initiate a signaling cascade that...
Enhancement of magnetic order in the incommensurate phase of Mg-doped CuGeO3 (2005)
Stock, C, Wakimoto, S, Birgeneau, RJ, Danilkin, S, Klenke, J, Smeibidl, P, ...
