Improved determination of the - angular correlation coefficient in free neutron decay with the SPECT spectrometer
M. Beck, F. Ayala Guardia, S. Baeßler +15
We report on a precise measurement of the electron-antineutrino angular correlation ( coefficient) in free neutron beta-decay from the SPECT experiment. The coefficient i…
Nuclear hyperpolarization of 3He by magnetized plasmas
A. Maul, P. Blümler, P. -J. Nacher +3
We describe a method to hyperpolarize 3He nuclear spins at high magnetic fields (4.7 Tesla) solely by a magnetized plasma. The conditions for such a magnetized plasma are fulfilled…
New limit on Lorentz and CPT violating neutron spin interactions using a free precession 3He-129Xe co-magnetometer
F. Allmendinger, W. Heil, S. Karpuk +6
We report on the search for a CPT and Lorentz invariance violating coupling of the 3He and 129Xe nuclear spins (each largely determined by a valence neutron) to background tensor f…
Measurement of the neutron electric to magnetic form factor ratio at Q2 = 1.58 GeV2 using the reaction 3He(e,e'n)pp
B. S. Schlimme, P. Achenbach, C. A. Ayerbe Gayoso +29
A measurement of beam helicity asymmetries in the reaction 3He(e,e'n)pp has been performed at the Mainz Microtron in quasielastic kinematics in order to determine the electric to m…
Test of Lorentz Symmetry by using a 3He/129Xe Co-Magnetometer
K. Tullney, C. Gemmel, W. Heil +11
To test Lorentz symmetry we used a 3He/129Xe co-magnetometer. We will give a short summary of our experimental setup and the results of our latest measurements. We obtained prelimi…
Measuring the proton spectrum in neutron decay - latest results with aSPECT
M. Simson, F. Ayala Guardia, S. Baeßler +11
The retardation spectrometer aSPECT was built to measure the shape of the proton spectrum in free neutron decay with high precision. This allows us to determine the antineutrino el…
