“…It may be pointed out that the theoretical calculations used in the present analysis are performed for a level density parameter a = A/8 MeV −1 . Further, the production of all the CF and ICF reaction products, identified in the present work, has also been reported by Singh et al [55], Sahoo et al [56] and Chakrabarty et al [57].…”

“…The variation of driving input angular momentum involved in the population of CF and ICF residues is discussed in terms of entrance-channel mass-asymmetry and target deformation. The present work not only provides the qualitative information of the driving input angular momentum associated with various reaction channels but also bolsters the earlier findings of ICF contribution in 12 C + 169 Tm reaction [56,57]. The experimental details and data reduction procedures are given in section 2.…”

The spin-distributions of different reaction products populated via x n and α/2αx n channels in C 12 + Tm 169 system have been measured at E lab ≈ 6, 7 and 7.5 MeV A−1 to disentangle complete and incomplete fusion events. Particle (p, α)-γ-coincidences were recorded to identify evaporation residues channel-by-channel. The spin-distributions of fusion evaporation and direct-α-emitting channels are found to be distinct corroborating the involvement of entirely different reaction dynamics in their production, respectively termed as complete (CF) and incomplete fusion (ICF). The values of mean input angular momenta, obtained from the analysis of the spin-distributions, involved in ICF-α/2α xn channels are estimated to be larger than that observed in CF-xn/α xn channels. For ICF-α/2αxn channels, the multiplicity of fast-α particle emission increases with the magnitude of input angular momentum imparted into the system. The CF residues display a population of broad spin range while the ICF residues are confined to a narrow spin range generally localized in the higher spin states. Findings of the present work conclusively demonstrate the possibility to populate high spin states in final reaction products using ICF, which are otherwise not accessible. Further, an attempt has been made to study the variation of input angular momentum with the choice of different entrance-channel parameters. It has been observed that the value of input angular momentum involved in ICF-α/2α xn channels increases with the deformation and entrance-channel mass-asymmetry parameter, indicating strong entrance-channel dependence of ICF dynamics.

“…The fusing nucleus can be either of the projectile fragments, however in the test cases used with PLATYPUS, a constant α fusing particle was used to compare the effectiveness of different initial projectiles. Additionally, larger observer nuclei can break up further, such as 16 O into four α-cluster nuclei [64]. However, for the purpose of maximising the additional torque in the fusing particle, this breakup is assumed not to occur.…”

Using a classical dynamical reaction model, angular momentum (L) values of a compound nucleus due to incomplete fusion (ICF) 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 α-cluster fuses with a 208Pb target, forming an excited 212Po compound nucleus. Results show that all ICF reactions produced higher angular momentum in the compound nucleus compared to a direct beam of α particles at the same incident energy. The highest angular momentum values produced in 212Po for near and above Coulomb barrier energies were obtained using a 20Ne projectile at and , respectively. This produced 25% and 50% L values above the next highest-Z projectile used, 8Be, respectively.
