    A Study of Incomplete Fusion Reaction and its Correlation with Projectile Energy and Entrance channel Mass-Asymmetry in some 12C/16O-Induced Reactions at ≈3–9 MeV/nucleon
    (HAWASSA UNIVERSITY, 2024-05) Mustefa Kedir Dubiso
    In this work, the effects of projectile energy and entrance channel mass-asymmetry on incomplete fusion reaction in 12C + 128Te, 12C + 141Pr, 12C + 159Tb, 16O + 130Te, 16O + 159Tb and 16O + 181Ta, projectiles + targets systems at ≈ 3-9 MeV/nucleon were studied. Cross sections of various reaction products populated via complete and incomplete fusion of 12C projectile with 128Te, 141Pr and 159Tb-targets and 16O projectile with 130Te, 159Tb and 181Ta targets were calculated using the reaction model code PACE4. The predicted cross sections were compared with experimentally measured data from EXFOR database. For a representative non α-emitting ( 12C, 4n) channel from a representative in 12C + 159Tb system, experimentally measured cross sections agreed with PACE4 prediction for level density parameters K=10. For the same level density parameters a representative α-emitting (12C, α3n) from a representative in 12C + 128Te projectile + target system, the experimentally measured cross sections are higher than the PACE4 predicted. The observed difference is attributed to the contribution of incomplete fusion following the prompt break-up of the projectiles into α-clusters. An attempt was made to deduce the contribution of incomplete fusion reactions from presently investigated projectile and target systems. It was found that the incomplete fusion fraction, in general, increases with the increase in projectile energy. Furthermore, the result indicated that at the same normalized relative velocity, the incomplete fusion fraction is higher for mass-asymmetric projectiles and targets systems
