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…
Distillation of hydrogen isotopes for polarized HD target
T. Ohta, S. Bouchigny, J. -P. Didelez +13
We have developed a cryogenic distillation system to purify Hydrogen-Deuteride (HD) gas for a polarized HD target in LEPS experiments at SPring-8. A small amount of ortho-H ($\…
Development of portable NMR polarimeter system for polarized HD target
T. Ohta, M. Fujiwara, K. Fukuda +10
A portable NMR polarimeter system has been developed to measure the polarization of a polarized Hydrogen-Deuteride (HD) target for hadron photoproduction experiments at SPring-8. T…
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…
Measurements of ultracold neutron lifetimes in solid deuterium
C. L. Morris, J. M. Anaya, T. J. Bowles +24
We present the first measurements of the survival time of ultracold neutrons (UCNs) in solid deuterium SD2. This critical parameter provides a fundamental limitation to the effecti…
