21. Search for a T-odd, P-even Triple Correlation in Neutron Decay
Topic: Radiation Physics
Published: 9/14/2012
Authors: 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
Abstract: 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 ...

22. In-situ Polarized 3He system for the Magnetism Reflectometer at the Spallation Neutron Source
Topic: Radiation Physics
Published: 7/2/2012
Authors: Thomas R Gentile, X Tong, C Y Jiang, V Lauter, H. Ambaye, D. Brown, L Crow, R J Goyette, W-T Lee, A. Parizzi
Abstract: 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 ...

23. Measurements for the Development of Simulated Naturally Occurring Radioactive Materials
Series: Journal of Research (NIST JRES)
Report Number: 117.008r2012
Topic: Radiation Physics
Published: 4/3/2012
Author: Leticia S Pibida
Abstract: 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 ...
