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…

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…

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…

Search for the lepton-family-number nonconserving decay μ-> e + γ

M. Ahmed

The MEGA experiment, which searched for the muon- and electron-number violating decay μ-> e + γ, is described. The spectrometer system, the calibrations, the data taking procedures…

New Limit for the Family-Number Non-conserving Decay mu+ to e+_gamma

MEGA Collaboration, M. L. Brooks, Y. K. Chen +25

An experiment has been performed to search for the muon- and electron-number non-conserving decay mu+ to e+_gamma. The upper limit for the branching ratio to be GAMMA(mu+ to e+_gam…
