The primary fragment mass-yield distribution for the asymmetric fission path in heavy nuclei, Pa-233, Np-239, Am-245 and Bk-249 at the excitation energy of similar to20 MeV are experimentally constructed based on the intensities of total kinetic energies for individual mass splits. The results revealed an interesting phenomenon: in all the studied fissioning systems, the inner wings of the mass-yield distributions in the asymmetric fission path appear along the same mass-wall of A = 130 fragment mass. The asymmetric mass-yield distribution indicates the strong effect of structural shells in fragments on the final mass division process of the asymmetric fission path.
