Detecting the radiative decay mode of the neutron
Precision measurements of neutron beta decay correlations, a, b, B, and A, provide important tests of the electroweak standard model: a test of unitarity of the first row of the CKM matrix, a test of the CVC hypothesis, and a sensitive search for right-handed currents or scalar or tensor bosons.
