Both in-plane and out-of plane angular correlations of coincident C and ..cap alpha.. particles have been measured for 65-MeV /sup 16/O bombardment of an /sup 27/Al target. Exploitation of the time-of-flight method enabled measurement of very-low-energy alpha particles at back angles. Results from the present experiment show that evaporation from an intermediate nucleus /sup 31/P* accounts for the majority of the C-..cap alpha.. coincidence events observed. A small number of alpha particles from the break-up of /sup 16/O* were detected at angles around that of the carbon detector. Fewer than 10% of the alpha particles detected are of pre-equilibrium origin. this finding is in sharp contrast to earlier results. 11 figures.
