Role of rotational energy component in the dynamics of 16O+198Pt reaction

The role of rotational energy is investigated in reference to the dynamics of 16 O+198 Pt →214 Rn∗ reaction using the sticking (I S ) and the non-sticking (I NS ) limits of moment of inertia within the framework of dynamical cluster decay model. The decay barrier height and barrier position get significantly modified for the use of sticking or non-sticking choice, which in turn reproduce the evaporation residue and the fusion-fission cross-sections nicely by the I S approach, while the I NS approach provides feasible addressal of data only for evaporation residue channel. Moreover, the fragmentation path of decaying fragments of 214 Rn∗ compound nucleus gets influenced for different choices of moment of inertia. Beside this, the role of nuclear deformations i.e. static, dynamic quadurpole (β2 ) and higher order static deformation up to β4 are duly investigated for both choices of the moment of inertia.
