Evaporation residue cross sections in the reaction of 16O+238U were measured for the energy range from above- to extreme sub-barrier as direct evidence of complete fusion. The cross sections are reproduced by a statistical-model calculation, for which partial cross sections are calculated by a coupled-channel model taking into account the prolate deformation of 238U. It is found that complete fusion occurs in the collision of the projectile with the tips of the 238U target, the same as in the side collision.
