Abstract
A value of (- 0.8 ± 2.5) × has been measured for the ratio of double-photon to single-photon emission following neutron capture in hydrogen for . The two Ge(Li) detectors used in the experiment subtended an angle of 85° at the O target and were shielded from each other to reduce the background from the cross registration of single rays. The upper limit of the measured two-photon cross section (-3 ± 8 μb) is two orders of magnitude larger than the most recent theoretical predictions ( μb) for this energy range.
