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…
Performance of the upgraded ultracold neutron source at Los Alamos National Laboratory and its implication for a possible neutron electric dipole moment experiment
T. M. Ito, E. R. Adamek, N. B. Callahan +23
The ultracold neutron (UCN) source at Los Alamos National Laboratory (LANL), which uses solid deuterium as the UCN converter and is driven by accelerator spallation neutrons, has b…
A new method for measuring the neutron lifetime using an in situ neutron detector
C. L. Morris, E. R. Adamek, L. J. Broussard +28
The neutron lifetime is important in understanding the production of light nuclei in the first minutes after the big bang and it provides basic information on the charged weak curr…
Position-sensitive detection of ultracold neutrons with an imaging camera and its implications to spectroscopy
Wanchun Wei, L. J. Broussard, M. A. Hoffbauer +29
Position-sensitive detection of ultracold neutrons (UCNs) is demonstrated using an imaging charge-coupled device (CCD) camera. A spatial resolution less than 15 m has been achie…
Determination of the Free Neutron Lifetime
J. David Bowman, L. J. Broussard, S. M. Clayton +24
We present the status of current US experimental efforts to measure the lifetime of the free neutron by the "beam" and "bottle" methods. BBN nucleosynthesis models require accurate…
Measurement of the half-life of the T= mirror decay of Ne and its implication on physics beyond the standard model
L. J. Broussard, H. O. Back, M. S. Boswell +19
The superallowed mixed mirror decay of Ne to F is excellently suited for high precision studies of the weak interaction. How…
Baryon Number Violation
K. S. Babu, E. Kearns, U. Al-Binni +93
This report, prepared for the Community Planning Study - Snowmass 2013 - summarizes the theoretical motivations and the experimental efforts to search for baryon number violation,…
The Upscattering of Ultracold Neutrons from the polymer
E. I. Sharapov, C. L. Morris, M. Makela +28
It is generally accepted that the main cause of ultracold neutron (UCN) losses in storage traps is the upscattering to the thermal energy range by hydrogen adsorbed on the surface…
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…
