Abstract:
In the last years the quantity and quality of experimental data of new super-heavy nuclei (SHN) have increased considerably. These nuclei have now become available for experimental studies with in-beam and decay spectroscopic methods, and also for detailed investigations through a variety of phenomenological and theoretical approaches [1-2]. The comparison of the behavior of measured AD properties with predictions from two theoretical approximations with and without the microscopic structure of involved nuclei provides a unique information on the clustering and reaction amplitudes [3].
Half-lives predictions are made for unknown nuclei near closed shells with Z=50, 82, 108, 120, and N=50, 126, 172 [4-5].
