Final results for the neutron -asymmetry parameter from the UCNA experiment
B. Plaster, E. Adamek, B. Allgeier +91
The UCNA experiment was designed to measure the neutron -asymmetry parameter using polarized ultracold neutrons (UCN). UCN produced via downscattering in solid deuterium w…
Search for dark matter decay of the free neutron from the UCNA experiment: n
X. Sun, E. Adamek, B. Allgeier +57
It has been proposed recently that a previously unobserved neutron decay branch to a dark matter particle () could account for the discrepancy in the neutron lifetime observed i…
New result for the neutron -asymmetry parameter from UCNA
M. A. -P. Brown, E. B. Dees, E. Adamek +56
The neutron -decay asymmetry parameter defines the correlation between the spin of the neutron and the momentum of the emitted electron, which determines $λ=\frac{g_{A}}{g…
Measurements of ultracold neutron upscattering and absorption in polyethylene and vanadium
E. I. Sharapov, C. L. Morris, M. Makela +27
The study of neutron cross sections for elements used as efficient ``absorbers'' of ultracold neutrons (UCN) is crucial for many precision experiments in nuclear and particle physi…
Measurement of the neutron -asymmetry parameter with ultracold neutrons
UCNA Collaboration, B. Plaster, R. Rios +43
We present a detailed report of a measurement of the neutron -asymmetry parameter , the parity-violating angular correlation between the neutron spin and the decay electron…
Determination of the Axial-Vector Weak Coupling Constant with Ultracold Neutrons
UCNA Collaboration, J. Liu, M. P. Mendenhall +37
A precise measurement of the neutron decay -asymmetry has been carried out using polarized ultracold neutrons (UCN) from the pulsed spallation UCN source at the Los Alamos…
First Measurement of the Neutron -Asymmetry with Ultracold Neutrons
R. W. Pattie
We report the first measurement of angular correlation parameters in neutron -decay using polarized ultracold neutrons (UCN). We utilize UCN with energies below about 200 neV, w…
