The possibility of heavy particle radioactivity (heavier clusters) in ground state decays of 287−289115 parent nuclei, resulting in a doubly magic daughter around 208Pb is analyzed using Preformed Cluster Model (PCM) with choices of spherical and quadrupole deformation (β2) having “optimum” orientations of decay products. The behavior of fragmentation potential and preformation probability is investigated in order to extract better picture of the dynamics involved. Interestingly, the potential energy surfaces obtained via the fragmentation process get modified significantly with the inclusion of deformation and orientation effects, which in turn influence the preformation factor.
