We present the fusion of series of reactions of isotopes/isotones leading to the same compound nucleus. This is achieved by transferring either neutrons or protons from one to the other colliding nucleus. Our findings for the normalized barrier heights, positions as well as fusion cross-sections suggest that such fusion of transfer reactions can be parameterized in terms of an asymmetry power law with power factor close to two. This power factor is nearly the same as has been reported for the asymmetric term in mass formula.
