Abstract

Mass–energy distributions of binary fragments produced in the \({}^{90}\textrm{Zr}+{}^{90}\)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 \({}^{36}\textrm{Ar}+{}^{144}\)Sm and \({}^{68}\textrm{Zn}+{}^{112}\)Sn reactions leading to the formation of the same compound system \({}^{180}\)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\(\%\).
