Abstract

The role of rotational energy is investigated in reference to the dynamics of ¹⁶O+¹⁹⁸Pt →²¹⁴Rn^∗ 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 ²¹⁴Rn^∗ 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.
