Nuclear-Spin Dependent Parity Violation in Optically Trapped Polyatomic Molecules

July 3, 2019
Author(s)
Eric B. Norrgard, Daniel S. Barker, Stephen P. Eckel, James A. Fedchak, Nikolai N. Klimov, Julia K. Scherschligt
We investigate using optically trapped linear polyatomic molecules as probes of nuclear spin- dependent parity violation. The presence of closely spaced, opposite-parity $\ell$-doublets is a general feature of such molecules, allowing parity-violation

First application of superconducting transition-edge-sensor microcalorimeters to hadronic-atom x-ray spectroscopy

September 30, 2016
Author(s)
Douglas Bennett, W.Bertrand (Randy) Doriese, Joseph Fowler, Johnathon Gard, James P. Hays-Wehle, Gene C. Hilton, Carl D. Reintsema, Daniel Swetz, Joel Ullom
High-resolution pionic-atom x-ray spectroscopy was performed with an x-ray spectrometer based on a 240-pixel array of superconducting transition-edge-sensor (TES)microcalorimeters at the πM1 beam line of the Paul Scherrer Institute. The pionic-carbon 4 → 3

Strength of Silicon, Sapphire in the Subthreshold Flaw and Glass Region

July 1, 2004
Author(s)
Yeon-Gil G. Jung, Antonia Pajares, R Banerjee, Brian R. Lawn
Strength properties are determined for monocrystalline silicon and sapphire and for soda-lime glass plates containing subthreshold flaws, i.e. flaws without detectable microcracks. Nanoindentations covering a wide range of loads are used to introduce flaws

Surface and Interface Properties of UV-Exposed PVDF/PMMA-CO-PEA Blends

March 5, 2003
Author(s)
Xiaohong Gu, Li Piin Sung, D L. Ho, Chris A. Michaels, D Nguyen, Y C. Jean, Tinh Nguyen
The surface and interface of PVDF blended with different amounts of poly (methyl methacrylate) and poly (ethyl acrylate) copolymer (PNMA-co-PEA) have been investigated before and after exposure to UV light. Dry free films having athickness of approximately

The Formation of Whiskers on Electroplated Tin

December 1, 2001
Author(s)
Kil-Won Moon, Maureen E. Williams, C E. Johnson, Gery R. Stafford, C A. Handwerker, William J. Boettinger
… from 0 to 35 x 10(super-3) mole. To provide reproducible plating conditions and to approximate flow conditions in commercial strip plating, a rotating disk electrode assembly was used. Substrates for plating were pyrophosphate Cu and silicon (Si) single crystal …

Single photon sources based on single quantum dots

August 8, 2004
Author(s)
Richard P. Mirin
We describe temperature-dependent photon antibunching measurements from single InGaAs/GaAs quantum dots. The second order intensity correlation demonstrates single emitter emission up to 120 K and nonclassical light emission to 135 K.
