A modified statistical analysis is proposed to account for the enhanced back angle scattering for certain heavy ion collisions. The fluctuation differential cross section, influenced by barrier top resonances, is predicted to approach a Vertical BarP/sub l/0(theta)Vertical Bar/sup 2/(theta) form, where l/sub 0/ is the orbiting angular momentum. A statistical expression for the magnitude of the 180/sup 0/ fluctuation cross section is derived and applied to the /sup 16/O+/sup 28/Si and /sup 12/C+/sup 28/Si elastic scattering at 30 MeV (c.m.). Numerical estimates, based on parameters in the literature, are found in qualitative agreement with observation.
