Effect of the Critical Angular Momentum on Incomplete Fusion Dynamics

Abstract

An attempt has been made to calculate the critical angular momentum (ℓ_crit) 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 ℓ_crit values are slightly lower than the theoretically calculated values at projectile energies from 66 to 114 MeV. the low values of ℓ_crit 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 ℓ_crit-values are consistent with theoretically calculated values. this shows that ℓ_crit -values associated with ICf channels for this system suggests that at these projectile energies, ICf may be associated with peripheral collision.
