Abstract
The role of isoscalar giant quadrupole excitations in as doorway states for symmetric fission and intermediate structure resonances in + elastic scattering is investigated by means of model calculations using particle-hole excitations over two major shells. The fission mode is treated as a shape degree of freedom that couples the giant quadrupole resonances in to the ground state. The associated intermediate-structure resonances have calculated widths for symmetric fission and decay that are in qualitative agreement with experiment.
