Abstract
An upper limit of has been obtained for the branching ratio for the emission of two photons ( MeV) following thermal neutron capture in hydrogen. This limit was obtained with two Ge(Li) detectors shielded so as to reduce -ray scattering from one detector into the other and is a factor of 10 lower than has been recently reported.
