Neutron--charged-particle correlations in the 3. 8 MeV per nucleon sup 16 O+ sup 12 C and 13. 4 MeV per nucleon sup 16 O+ sup 27 Al reactions
Neutron--light-charged-particle (LCP) and LCP-LCP correlation functions were measured for the 215 MeV {sup 16}O+{sup 27}Al reaction, together with the neutron-proton correlation function for the {sup 16}O+{sup 12}C reaction at {ital E}{sub lab}=60.5 MeV. The {ital np} and {ital pp} correlation data...

| description | Neutron--light-charged-particle (LCP) and LCP-LCP correlation functions were measured for the 215 MeV {sup 16}O+{sup 27}Al reaction, together with the neutron-proton correlation function for the {sup 16}O+{sup 12}C reaction at {ital E}{sub lab}=60.5 MeV. The {ital np} and {ital pp} correlation data are compared with the predictions of the Koonin model and a semiclassical evaporation model. Both models provide an excellent fit to the {ital np} data, while the {ital pp} data are not reproduced as well. Production yields of singlet deuterons, ground state {sup 5}He and {sup 5}Li, and {sup 6}Li nuclei in the 2.186 MeV state were obtained from the coincidence data, and a nuclear temperature of {ital T}=2.0{sub {minus}0.6}{sup +0.8} MeV for the {sup 16}O+{sup 27}Al compound system was determined from the ratio of singlet to ground state deuteron emission, after corrections for sequential emission and noncompound deuteron production. This temperature value is well below the Fermi gas model estimate, and a similar result is observed for the {sup 16}O+{sup 12}C compound system. |
