Abstract:
Particle (p, α)–γ-coincidence experiment has been performed to probe
incomplete fusion dynamics in the 12C+169Tm system at 5–7.5 MeV/A.
Spin distributions of different reaction products populated via xn and
α/2αxn channels have been measured to acquire information about the
involved reaction mechanism on the basis of their experimentally observed
de-excitation patterns. The spin distributions of direct-α (incomplete fusion) and fusion–evaporation (complete fusion) channels are found to be
distinct from each other, substantiating their origin in entirely different reaction dynamics. It has been found that CF products span a broad spin
range, while ICF products are confined to a narrow spin range localized
in the higher spin states. Findings of the present work comprehensively
demonstrate that incomplete fusion reactions can be used as a sensitive
tool to populate high-spin states in final reaction products, which are not
otherwise accessible.
