Analysis of heavy-ion reactions using projection operators
A projection operator method based on the Feshbach doorway approach is developed for low-energy heavy-ion scattering. Applications to /sup 12/C+/sup 12/C and /sup 12/C+/sup 16/O are made with doorways taken as quasibound or virtual states of the reduced mass coupled to 2/sup +/ and 3/sup -/ vibrations. For /sup 12/C+/sup 12/C the elastic differential cross section at 90/sup 0/ c.m. is calculated. For /sup 12/C+/sup 16/O we calculate the ratio of the differential cross section to the Rutherford cross section at a range of angles between 90/sup 0/ and 160/sup 0/ c.m. In both cases the calculations agree well with experiment by producing both the gross and intermediate molecular structure. The conditions under which intermediate structure can be expected are discussed.
