Abstract:The properties of toroidal hyperheavy even-even nuclei and the role of toroidal shell structure are extensively studied within covariant density functional theory. The general trends in the evolution of toroidal shapes in the Z ≈ 130 − 180 region of nuclear chart are established for the first time. These nuclei are stable with respect of breathing deformations. The most compact fat toroidal nuclei are located in the Z ≈ 136, N ≈ 206 region of nuclear chart, but thin toroidal nuclei become dominant with increas… Show more
