Abstract:
Absolute cross sections for 22 fissionlike fragments concerning their decay mode via independent and
cumulative cross sections have been measured at four projectile energies, i.e., 82.2 ± 0.8, 79.18 ± 0.82, 76.8 ±
1.2, and 72.9 ± 0.91 MeV. The recoil-catcher activation technique followed by offline γ -ray spectrometry was
employed. The isotopic yield distribution and the variance for indium isotopes have been obtained from the
experimental data and were found to be in agreement with the literature values. The fissionlike fragments mass
distribution is found to be a single-peaked Gaussian distribution and confirms their population via deexcitation
of the compound nucleus. The mass distribution variance is found to be narrower and exponentially increases
as compared to relatively heavier systems at above 20% of the Coulomb barrier. A self-consistent approach for
determining the isobaric charge dispersion parameters has been adopted. The present paper suggests that fission
is one of the competing modes at low energies other than complete fusion and incomplete fusion processes.
