Fusion reactions of the neighboring nuclei systems, i.e., C12 on C12, N14, O16, O18, and F19 were analyzed. In the low energy regions, it is pointed out that a commonly used parametrized form has various insufficiencies. Use of the four kinds of potentials, Woods-Saxon, single-folding, double-folding, and proximity potentials were examined, and all show a unique trend of gradually increasing radii among these systems. In the high energy regions, decreasing cross sections towards higher incident energies cannot be explained in general by the staightforward yrast cut off treatments, although they are close in these light nuclei systems. If the partial waves are limited for those having the minima of their potential pockets inside the half density distance predicted by the proximity potential, the experimental data can be fitted. NUCLEAR REACTIONS Analyses of fusion reactions: C12+C12, C12+N14, C12+O16, C12+O18, C12+F19; potential model using Woods-Saxon, single-folding, double-folding potentials: yrast cutoff, critical distance in the proximity potential.
