Influence of sticking vs non-sticking limits of moment of inertia and higher order deformations in the decay of 214,216Rn ? compound systems

摘要

AbstractThe dynamical cluster decay model (DCM) is employed to explore the relative effect of sticking (IS) and non-sticking (INS) limits of moment of inertia (MOI) in the decay of hot and rotating214,216Rn?compound nuclei, formed in16,18O +198Pt reactions. Beside this, the nuclear deformation effects i.e. quadrupoleβ2(static and dynamic) and higher order static deformations up to hexadecapole (β4) are duly incorporated and studied within DCM. The influence of both ‘INS/IS’ addressing rotational energy component and ‘deformations’ is gauged through the barrier characteristics, preformation factor and barrier lowering effects. The experimentally given ER and ff data is addressed by optimizing the neck-length ΔR, that strongly depends on the limiting angular momentum, which in turn depends on the sticking or non-sticking limits of interaction. In addition to this, the influence of increase in energy and neutron number is probed in reference to ER survival probability of Rn compound nucleus. Finally, the ff cross-sections of214,216Rn?nuclei are predicted within sticking limit of moment of inertia as the same seems to be more suitable for such decay paths.]]>
