Phase transitions for rotational states within an algebraic cluster model
E. Lopez-Moreno · P. O. Hess · H. Yepez-Martinez
Abstract
The catastrophe theory, an effective method for the description of phase transitions, is applied to the Semimicroscopic Algebraic Cluster Model (SACM) as an example of a non-trivial theory. The ground state and excited, rotational phase transitions are investigated. A short introduction to the SACM and the catastrophe theory is given. We apply the formalism to the test case of 16O+alpha-->20Ne.
