The projected multi-dimensionally-constrained relativistic Hartree-Bogoliubov model was employed to calculate the potential energy surface of the high-spin states in 56Ni. It is pointed out for the first time that possible octupole deformations exist for the positive and negative parity superdeformed bands in 56Ni, with deformations β30∼0.14 and β30∼0.24, respectively, along with a large prolate deformation of β20∼ 0.42. These octupole deformations are induced by the coupling between 2p3/2 and 1g9/2 orbits at the deformation β20∼ 0.4. The calculated excitation energies of the two rotational bands are consistent with the observed superdeformed bands of 56Ni. In addition, two rotational bands are predicted, consisting of one superdeformed band with negative parity and one hyperdeformed bands with positive parity.
