Abstract
Using a classical dynamical reaction model, angular momentum (\textit{L}) values of a compound nucleus due to incomplete fusion at energies near and above the Coulomb barrier are studied. In this model, a projectile consisting of two cluster nuclei is fired at a stationary target nucleus. After breakup of the projectile due to Coulombic and nuclear forces, an \(\alpha\)-cluster fuses with a \textsuperscript{208}Pb target, forming an excited \textsuperscript{212}Po compound nucleus. Results show that all incomplete fusion reactions produced higher angular momentum in the compound nucleus compared to a direct beam of \(\alpha\) particles at the same incident energy. The highest angular momentum values produced in \textsuperscript{212}Po for near and above Coulomb barrier energies were obtained using a \textsuperscript{20}Ne projectile, at 16\(\hbar\) and 40\(\hbar\) respectively. This produced 25\% and 50\% \textit{L} values above the next highest-Z projectile used, \textsuperscript{8}Be, respectively.
