To that end we apply a theory of adiabatic large-amplitude motion to a simplified nuclear shell-model, where the approximate results can be contrasted with exact diagonalisations. We find excellent agreement for different regimes, and contrast the results with those from a more standard calculation using a quadrupole constraint. We show that the method employed in this work selects diabatic (crossing) potential energy curves where these are appropriate, and discuss the implications for a microscopic study of shape coexistence.", "revisions": [ { "version": "v1", "updated": "1998-07-30T21:24:45.000Z" } ], "analyses": { "keywords": [ "shape coexistence", "collective coordinates", "shape transitions", "microscopic approach", "potential energy curves" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
