Analysis of a hyperdeformed band of 152(66)Dy86 on the basis of a structure with two revolving clusters, each with a previously unrecognized two-tiered structure.
Analysis on the basis of the two-revolving-cluster model has been made of a cascade of 11 gamma-rays constituting a hyperdeformed band of 152(66)Dy86 (or possibly 153Dy) reported by Galindo-Uribarri et al. [Galindo-Uribarri, A., et al. (1993) Phys. Rev. Lett. 73, 231-234], leading to the conclusions that the band extends from values K approximately 82-104 for the angular-momentum quantum number, that the moment of inertia is approximately 5650 Da.fm2, that the composition of the central sphere is p40n50 and that of each of the clusters is p13n18, that each of the clusters consists of two tiers of spherons, and that the radii of revolution of the inner and outer tiers have values of about 8.00 and 11.20 fm, respectively.
