The back-angle yields of the oxygen and carbon particles from the /sup 24/Mg+ /sup 16/O reaction have been measured at E/sub lab/( /sup 24/Mg) = 79.5 MeV by using reverse kinematics. Comparison with data for the /sup 28/Si+ /sup 12/C reaction forming the same compound nucleus at the same excitation energy and with very similar spin distribution demonstrates a strong entrance channel effect which is favoring the breakup into the entrance channel with large excitation energy. This result qualitatively supports the picture of the formation of a long-lived orbiting complex whose structure and decay is dependent on the entrance channel. The compound nucleus contribution has been inferred to be less than 15% of the measured oxygen cross section.
