摘要

【正】 The ¹⁶O（n,γ）¹⁷O reaction is first realized at neutron energies from 7 to 14MeV,which is the so-called pygmy resonance region.The pusled beam and time offlight techniques are used.Two large NaI-plastic anticoincidence shielded spectrometersare used to detect high energy gamma rays.The results are in good agreement withthose of the ¹⁷O（γ,n₀）reaction by detailed balance.The integrated（γ,n₀）cross section is5.88 MeV mb,which is 2.3% of energy weighted sum rule（EWSR）.
