Each beta decay produces not only an electron but also an invisible neutrino, and researchers have long relied on measurements of beta-decay
spectra for information about the accompanying neutrinos.
Neutron decays are detected in real time using the scintillation light produced in the helium by the beta-decay
This provided a further handle on the separation of wall losses from beta-decay
lifetime of the neutrons has a direct impact on cosmological models as a production of light elements during the Big Bang.
An experiment to study the radiative beta-decay
of the neutron is currently being developed for the NG-6 fundamental physics endstation at the National Institute of Standards and Technology (NIST) Center for Neutron Research (NCNR).
In addition, cells with highly uniform gas thickness are required to produce the spatially uniform neutron polarization needed for beta-decay
correlation coefficient experiments.
