Experimental Study of Mass–Energy Distribution of Fragments Produced in the Zr Reaction Leading to the Formation of Hg at Energies near the Coulomb Barrier.

Mass–energy distributions of binary fragments produced in the Zr reaction at the projectile-ion energy of 378 MeV were measured by means of the CORSET double-arm time-of-flight spectrometer. From a comparison of the mass–energy distributions measured in the present study with the distributions of fragments produced in the Sm and Sn reactions leading to the formation of the same compound system Hg, it was found that the contribution of the fusion–fission process involving a compound nucleus to the total distribution of fission-like fragments was less than 20 .
