Abstract

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%.
