beta decay

a type of radioactivity that results in the emission of beta particles, either electrons or positrons. See also beta particle.

beta decay

Low-level radioactive decay in which particles, usually an electron with an antineutrino, or less commonly a positron with an antineutrino, are emitted.

Nevertheless, I think the argument that theories about the structure of space or set-theory are not terribly relevant to, for instance, explanations of Beta-decay, has some intuitive force, even if holism of some sort is admitted (provided it is not of the extreme sort that has no means of assessing or allowing for higher and lower degrees of relevance of theories of one subject matter to theories of another).
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.
Sturrock's team found a correlation between the fluctuation patterns and the data from the Super Kamiokande, which led them to the likely conclusion that neutrinos from the sun directly affected beta-decays.
1), consistent with the known neutron beta-decay lifetime.
The 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).
