Fusion measurements in light and medium mass heavy-ion reactions: Progress report for the period of June 1, 1986-May 31, 1987
The analysis of the fusion-evaporation cross section for /sup 24/Mg + /sup 24/Mg has been completed. As with other symmetric heavy-ion systems, this cross section appears to follow the prediction of a limitation imposed by the onset of fission. Much time has been spent on investigations of target-projectile systems leading to the /sup 56/Ni compound nucleus, /sup 16/O + /sup 40/Ca, /sup 32/S + /sup 24/Mg, and /sup 28/Si + /sup 28/Si. Status reports on earlier experiments in the final stages of analysis or being prepared for publication are given, as well as a description of a recent experiment on /sup 16/O + /sup 40/Ca at 15 MeV/A. In this experiment, coincidences between light nuclei and heavy residues and between pairs of heavy residues were obtained, as well as inclusive spectra of heavy residues and of complex light nuclei. A continuation of the search for production of n-p pairs emitted from fusion reactions in the /sup 1/S/sub 0/ deuteron state is reported. While this search is still unsuccessful, interesting information about the emission of nucleons from the /sup 28/Si compound nucleus has been obtained. An investigation of incomplete fusion, using /sup 12/C on heavy targets from /sup 90/Zr to /sup 197/Au, has been extended to ATLAS energies. While the initial run was not very successful, some useful data were obtained and a future run is planned. Efforts in the development and improvement of scintillation detectors for identification of Z = 1 and 2 nuclei from heavy-ion interactions have continued. 37 refs., 13 figs., 2 tabs.
