摘要：

Hyperdeformed minima in the actinide nuclei are discussed with the shell correction approach. Calculations are carried out in a large deformation space which makes it possible to provide a realistic description of very elongated shapes up to the fission saddle point. It is shown that the density distribution at the third, hyperdeformed minimum resembles a di-nucleus consisting of a nearly-spherical nucleus around the doubly-magic nucleus 132Sn, and a well-deformed fragment from the neutron-rich A approximately 100 region.
