ABSTRACT: Complete
and incomplete fusion cross sections have been measured for the 20Ne
+ 51V system to investigate the influence of projectile break-up at
or above the barrier energies. The excitation function of the individual
reaction channel measured using off-line γ-ray
spectroscopy has been compared with those estimated theoretically using the
statistical model code PACE4. A significant fraction of incomplete fusion has
been found in the production of residues involving α-particle in the exit channel. In order to understand the energy
dependence of incomplete fusion reactions, incomplete fusion fraction has been
deduced, which has also been compared with the earlier data available for 12C
and 16O projectiles to look for the projectile structure dependence.
