Projection operator methods are used to obtain the elastic differential scattering cross section at 90/sup 0/ c.m. for /sup 28/Si+ /sup 28/Si in the region E/sub lab/ = 100--120 MeV. Good agreement with the energies and structures of resonances seen experimentally is obtained by introducing doorway states for l = 34--38 constructed from a particle-vibration model that includes both the 2/sup +/ and 3/sup -/ excitation energies of /sup 28/Si. The sudden approximation is used in deriving the ion-ion potential and the density distribution is investigated. The calculated cross sections and widths support the association of the resonances with nuclear molecular formation.
