11. Polarized neutron beam properties for measuring parity-violating spin rotation in liquid He4
A M. Micherdzinska, C. D. Bass, T. D. Bass, K. F. Gan, D Lou, D M Markoff, Hans P Mumm, Jeffrey S Nico, A. K. Opper, E I Sharapov, M Snow, H E Swanson, V Zhumabekova
Measurements of parity-violating neutron spin rotation can provide insight into the poorly nderstood nucleon-nucleon weak interaction. Because the expected rotation angle per unit length is small (10−7 rad/m), several properties of the polarize ...
12. Progress Towards a Precision Measurement of the Neutron Lifetime Using Magnetically Trapped Ultracold Neutrons
P.-N. Seo, Kevin J Coakley, J M Doyle, F H DuBose, R Golub, E Korobkina, S K Lamoreaux, Hans P Mumm, C M O'Shaughnessy, G R Palmquis, A K Thompson, Grace L Yang, L Yang, Paul R Huffman
As part of an on-going program utilizing magnetically trapped ultracold neutrons (UCNs,) we are developing a technique that offers the possibility of improving the precision of the neutron lifetime by more than an order of magnitude. The experiment w ...
13. Radiative Beta Decay of the Free Neutron
R L Cooper, T E. Chupp, Maynard S Dewey, Thomas R Gentile, Hans P Mumm, Jeffrey S Nico, Alan K Thompson, B M Fisher, I Kremsky, F E. Wietfeldt, E J Beise, H Breuer, K G Kiriluk, J Bryne, Kevin J Coakley, Changbo Fu
The theory of quantum electrodynamics predicts that the beta decay of the neutron into a proton, electron, and antineutrino is accompanied by a continuous spectrum of emitted photons described as
inner bremsstrahlung. While this phenomenon has been ...
14. Radiative Decay Mode of the Free Neutron
Jeffrey S Nico, Maynard S Dewey, Thomas R Gentile, Hans P Mumm, Alan K Thompson, B M Fisher, I Kremsky, Fred E. Wietfeldt, T E Chupp, R L Cooper, E J Beise, K G Kiriluk, J Byrne, K Coakley
15. 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 ...
16. Testing Time-Reversal Symmetry in Neutron Beta Decay
Hans P Mumm, Maynard S Dewey, Jeffrey S Nico, Alan K Thompson, A Garcia, J F Wilkerson, S J Freedman, B K Fujikawa, T E Chupp, R L Cooper, C A Trull, Fred E. Wietfeldt, G L Jones
17. Time Reversal in Polarized Neutron Decay - The emiT Experiment
G L Jones, J M Adams, J M Anaya, T J Bowles, T E Chupp, K A Coulterpark, Maynard S Dewey, S J Freedman, B K Fujikawa, A Garcia, G L Greene, S -R Hwang, L Lising, Hans P Mumm, Jeffrey S Nico, R G Robertson, T D Steiger, W A Teasdale, Alan K Thompson, E G Wasserman, Fred E. Wietfeldt, J F Wilkerson
