High-spin yrast structure of 32S suggested by symmetry-unrestricted, cranked Hartree–Fock calculations Original Research Article

The high-spin yrast structure of 32S is investigated by means of the cranked Skyrme–Hartree–Fock method in the three-dimensional Cartesian-mesh representation without imposing restrictions on spatial symmetries. The result suggests that (1) a crossover from the superdeformed to the hyperdeformed-like configurations takes place on the yrast line at angular momentum I≃24, which corresponds to the “band termination” point in the cranked harmonic-oscillator model, and (2) non-axial octupole deformations of the View the MathML source type play an important role in the yrast states in the range 5≤I≤13.
