Experimental Study of Mass–Energy Distribution of Fragments Produced in the ^90Zr+^90 Zr Reaction Leading to the Formation of ^180 Hg at Energies near the Coulomb Barrier
Physics of Atomic Nuclei(2023)
摘要
Mass–energy distributions of binary fragments produced in the ^90Zr+^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 ^36Ar+^144 Sm and ^68Zn+^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 % .
