Description

Using two 25 cm diameter x 30 cm NaI spectrometers, coincidence γ-rays were observed attributed to the two-photon decay following thermal neutron capture by 3He (Q=20.6 MeV). The branching ratio sigma(2γ)/sigma(1γ) was measured to be 0.28+-0.07. This value is about ten times larger than the result of recent calculations. (Auth.)
