Abstract 

The phase diagram for the configuration mixed Interacting Boson Model is investigated for the special case of U(5)-O(6) mixing using the methods provided by Catastrophe Theory. It will be shown that this phase diagram exhibits properties not present when only a single configuration is considered.
