The total fusion cross section sigma/sub f/ for /sup 16/O + /sup 16/O has been measured in 500 keV steps between 12.5 and 30.5 MeV c.m. energy via ..gamma..-ray techniques. The excitation function for sigma/sub f/ shows clear evidence of periodic structure between 14 and 28 MeV (c.m.), as predicted by the optical model. These oscillations are out of phase with those observed in 90/sup 0/ elastic scattering. Individual yields of 12 nuclides formed in the reaction were also obtained. The narrow (GAMMA < or = 1 MeV) resonance at E/sub c.m./ = 26.5 MeV, which is correlated in the /sup 20/Ne and /sup 16/O (3/sup -/) channels, is suggested to be an ''..cap alpha..-exchange'' resonance.
