Complete and incomplete fusion cross sections for ⁶Li+²⁰⁹Bi reaction in multi-body classical molecular dynamical model

Using the multi-body Classical Molecular Dynamics simulation of ⁶Li+²⁰⁹Bi reaction it is shown that: (i) the breakup of a projectile fragment near the barrier leads to substantial increase in the ICF probabilities; (ii) the expected increase in σ_CF on relaxation of the rigid-body (RB) constraint on the projectile is compensated by reduction in the flux leading to CF, due to ICF events; (iii) the breakup probability increases with E_CM and, for given E_CM it also increases as b increases and peaks around some b>0, while cross sections σ_CF and σ_TF were calculated for b=0 only Therefore, we present the results of σ_CF (Complete Fusion) and σ_TF (Total Fusion) calculations which are obtained at critical impact parameter, b_cr, where many ICF channels open up and compare with the calculations performed at b=0 only, where only few ICF channels open up
