A New Neutron Lifetime Experiment with Cold Neutron Beam Decay in Superfluid Helium-4
Wanchun Wei
The puzzle remains in the large discrepancy between neutron lifetime measured by the two distinct experimental approaches -- counts of beta decays in a neutron beam and storage of…

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…
