Abstract

Small angle correlations between two neutrons emitted at a laboratory angle near 45° from the ¹⁶O+²⁷A1 reaction at 220 MeV have been measured. The results show a positive correlation peak centered near a relative momentum of 7.5 MeV/c. However, when restrictions are placed on the total momentum of the two-neutron system, the strength of the correlation function is found to be dependent on the total momentum of the two-neutron system. A possible anti-correlation is observed at low relative momentum for low total momentum pairs.
