Description 697-703
The present work aims to differentiate the contributions of complete fusion (CF) and incomplete fusion (ICF)
components by the measurement and analysis of the forward recoil range distribution of 20Ne projectile with 159Tb target
nucleus. The recoil catcher technique has been employed for the identification of residues populated in the collision of 20Neion
beam at projectile energy 8.2 MeV per nucleon. The result obtained from the study suggests that the complete fusion
reaction occurs with complete momentum transfer, which leads to large recoil ranges of the reaction products. However, the
presence of incomplete fusion, resulting from the break-up of 20Ne into 16O + 4He, 12C+ 8Be, and/or 8Be + 12C, involves
partial momentum transfer, leading to small recoil ranges where one of the fragments undergoes fusion with the 159Tb target
nucleus. Moreover, upon analyzing the data, the ICF fraction (FICF) has been estimated and compared with literature data as
a function of various entrance channel parameters, namely Mass-asymmetry (μMA), Coulomb factor (ZPZT), Deformation
parameter (2) and ZPZT2. The outcomes offer valuable insights into the entrance channel parameters that influence
incomplete fusion dynamics. Additionally, a new entrance channel parameter called Zeta (ζ) was introduced to investigate
the combined effect of μMA and ZPZT.
