On a biphononic origin of the 1125 cm^(-1) absorption band in cuprous oxide
V. M. Burlakov, M. Goeppert, A. Jolk +3
We report on the IR spectroscopic studies in both reflection (50-900 cm^{-1}) and transmission (900-3000 cm^{-1}) mode of the vibration spectrum of the cuprous oxide. A detailed an…
Weak Lensing by Large-Scale Structure with the FIRST Radio Survey
A. Refregier, S. T. Brown, M. Kamionkowski +5
The coherent image distortions induced by weak gravitational lensing can be used to measure the power spectrum of density inhomogeneities in the universe. We present our on-going e…
Elastic constants and volume changes associated with two high-pressure rhombohedral phase transformations in vanadium
B. Lee, R. E. Rudd, J. E. Klepeis +1
We present results from ab initio calculations of the mechanical properties of the rhombohedral phase (beta) of vanadium metal reported in recent experiments, and other predicted h…
One million year old groundwater in the Sahara revealed by krypton-81 and chlorine-36
N. C. Sturchio, X. Du, R. Purtschert +15
Measurements of 81Kr/Kr in deep groundwater from the Nubian Aquifer (Egypt) were performed by a new laser-based atom-counting method. 81Kr ages range from \~2x10^5 to ~1x10^6 yr, c…
The FIRST Efficient Gravitational Lens Survey
J. Lehar, A. Buchalter, R. McMahon +4
We have found three gravitational lenses (two are new) by observing 34 likely FIRST radio lobes with APM galaxy counterparts. We expect to find such lenses in over the nex…
Test Beam Performance Measurements for the Phase I Upgrade of the CMS Pixel Detector
M. Dragicevic, M. Friedl, J. Hrubec +481
A new pixel detector for the CMS experiment was built in order to cope with the instantaneous luminosities anticipated for the Phase~I Upgrade of the LHC. The new CMS pixel detecto…
