Approach to the rotation driven vibrational to axially rotational shape phase transition along the yrast line of a nucleus

By analyzing the potential energy surface, the shape phase diagram and the energy spectrum of the nucleus in U(5) symmetry in the IBM, we propose that the U(5) symmetry with parameters (A+B)<0 may be a model to describe the rotation driven vibrational to axially rotational phase transition along...

Summary:By analyzing the potential energy surface, the shape phase diagram and the energy spectrum of the nucleus in U(5) symmetry in the IBM, we propose that the U(5) symmetry with parameters (A+B)<0 may be a model to describe the rotation driven vibrational to axially rotational phase transition along the yrast line. With such a model, we have described successfully the observed rotation driven shape phase transition along the yrast line and proposed some other empirical evidences.
