Abstract
A novel analytically solvable prolate-oblate shape phase transitional description for the SU(3) limit of the interacting boson model is investigated for finite- as well as in the large- classical limit. It is shown that the ground state shape phase transition is of first order due to level crossing. Through a comparison of the theoretical predictions with available experimental data for even-even Hf, W, Os, and Pt, it is shown that this simple novel description is suitable for a description of the prolate-oblate shape phase transition in these nuclei.
