Jl. Egido et Lm. Robledo, Fission barriers at high angular momentum and the ground state rotational band of the nucleus No-254, PHYS REV L, 85(6), 2000, pp. 1198-1201
We study the superheavy nucleus No-254 in the framework of the Hartree-Fock
-Bogoliubov approximation with the finite-range density-dependent Gogny for
ce, at zero and high angular momentum. The properties of the ground state r
otational band and the fission barriers are discussed as a function of angu
lar momentum. We found a two-humped barrier up to spin values of (30-40)h a
nd a one-humped barrier for higher spins. We reproduce fairly well with the
binding energy, the ground state deformation, the gamma-ray energies, and
the bound on the fission barrier height measured at high spin.
