Fission of hyper-hyperdeformed $^{56}$Ni: a clustering analysis with in mean-field approaches

Abstract : The structure of 56Ni is sudied by using the non-relativistic Skyrme Hartree-Fock and the relativistic Hartree approximation in an axially deformed cylindrical coordinate. We found several intrinsic excited states, including the spherical ground-state solution. Without including any extra $\alpha$-cluster correlations, the possible cluster configurations of the resonance states are analyzed, showing the multipleN=Z, $\alpha$-nucleus like, cluster structures for hyper-deformed states, but, contrary to the recent experimental possibility of a ternary fission decay, we predict a two cluster or symmetric fission configuration for the hyper-hyperdeformed state
