Soft triaxial rotor in the vicinity of γ=π/6 and its extensions
L. Fortunato, S. De Baerdemacker, K. Heyde
Abstract
The collective Bohr hamiltonian is solved for the soft triaxial rotor around γ0=π/6 with a displaced harmonic oscillator potential in γ and a Kratzer-like potential in β. The properties of the spectrum are outlined and a generalization for the more general triaxial case with 0<γ<π/6 is proposed.
