21. Standardization of Broadband UV Measurements
George P Eppeldauer
The CIE standardized rectangular-shape UV response functions can be realized only with large spectral mismatch errors. The spectral power-distribution of UV sources is not standardized. Accordingly, the readings of different types of UV meters, even ...
22. Search for a T-odd, P-even Triple Correlation in Neutron Decay
Jeffrey S Nico, T E. Chupp, K P Coulter, R L Cooper, S. J. Freeman, B. K. Fujikawa, A. Garcia, G L. Jones, Hans P Mumm, Alan K Thompson, C A Trull, F. E Wiefeldt, J. F. Wilkerson
Time-reversal-invariance (T) violation, or equivalently, assuming charge-conjugation-parity-time-reversal (CPT) invariance, CP violation may explain the observed cosmological baryon asymmetry as well as signal physics beyond the Standard Model. In th ...
23. In-situ Polarized 3He system for the Magnetism Reflectometer at the Spallation Neutron Source
Thomas R Gentile, X Tong, C Y Jiang, V Lauter, H. Ambaye, D. Brown, L Crow, R J Goyette, W-T Lee, A. Parizzi
We report on the in-situ polarized 3He neutron polarization analyzer developed for the
time-of-flight Magnetism Reflectometer (MAGICS) at the Spallation Neutron Source
(SNS) at Oak Ridge National Laboratory (ORNL). Using the spin exchange optical
24. Measurements for the Development of Simulated Naturally Occurring Radioactive Materials
Journal of Research (NIST JRES)
Leticia S Pibida
Nineteen different commercially available samples containing naturally occurring radioactive
materials (NORM) (i.e., natural uranium, thorium, radium and potassium) were investigated, including
zircon sand, cat litter, roofing tiles, ice melt and ...
