Connecting the X(5)-${\beta }^2$, X(5)-${\beta }^4$, and X(3) models to the shape/phase transition region of the interacting boson model

E. A. McCutchan, Dennis Bonatsos, N. V. Zamfir

The parameter independent (up to overall scale factors) predictions of the X(5)-${\beta }^2$, X(5)-${\beta }^4$, and X(3) models, which are variants of the X(5) critical point symmetry developed…
