Two Particle Correlations from Neutron-Light Charged Particle Coincidences

The first correlation functions from a neutron--light-charged-particle small-angle coincidence measurement are reported for the {sup 16}O+{sup 27}Al reaction at {ital E}({sup 16}O)=215 MeV. Clear evidence for singlet-deuteron and {sup 5}He production, and an anticorrelation of low-relative-momentum neutron-dueteron pairs, is observed. The nuclear temperature of 1.6{plus minus}0.3 MeV, calculated from the ratio of excited-state to ground-state deuteron emission and corrected for sequential emission, is considerably lower than expected.
