Two topics from the wide field of nuclear few cluster studies are reviewed in this talk. They were chosen after a search revealed their prevalence in the literature from 1979–1983. Recent developments in the experimental and theoretical study of the six-nucleon system are discussed first. It is concluded that sufficiently comprehensive data sets are available to test the various theoretical models, which all show distinct deficiencies and must be improved. It is recommended that new experiments should only be carried out if the resolution of a specific, well-defined problem is attempted. The larger part of the talk is devoted to a critical review of the “molecular” (two-body) aspects of the interaction between lighter heavy ions (in particular 12C + 12C). Such fewbody aspects of HI collisions have never before been discussed at a Few Body Conference. An attempt is made to define the present status of the “molecular state” concept and to suggest directions for further, more conclusive experimental studies, based on well-tested methods used in few-body nuclear physics. |
