Bound-state β-decay of the neutron re-examined

RADIOACTIVITY ¹n(β^-); calculated observables of the bound-state β decay of neutron, branching ratio, probabilities, angular distributions of probabilities of hydrogen in the hyperfine states and proton-electron pair in different spinorial states. Discussed observables for experimental investigations of contributions of interactions beyond the Standard Model, and left-handed polarization state of antineutrinos.
