Effect of the Critical Angular Momentum on Incomplete Fusion Dynamics
An attempt has been made to calculate the critical angular momentum (ℓcrit) from the experimentally measured total ER cross-sections and are compared with Bass model predictions (using PACE-2). A comparison between experimentally measured and theoretically calculated critical angular momentum for the systems 16O + 45Sc and 16O + 74ge has been done. In case of 16O + 45Sc system, it is found that the experimentally measured ℓcrit values are slightly lower than the theoretically calculated values at projectile energies from 66 to 114 MeV. the low values of ℓcrit associated with ICf-channels for this system suggests that at these projectile energies, ICf may not be strictly associated with peripheral collision. Instead there appears to be deeper penetration of the projectile with the target at these beam energies. But for the system 16O +74ge at projectile energies from 65 to 112 MeV, the experimentally measured ℓcrit-values are consistent with theoretically calculated values. this shows that ℓcrit -values associated with ICf channels for this system suggests that at these projectile energies, ICf may be associated with peripheral collision.
