The magic numbers of the three-dimensional harmonic oscillator (2,8,20,40,70...) emerge at deformations around epsilon=0.6. At lower deformations the two sets of magic numbers antagonize, leading to shape coexistence. A quantitative investigation is performed using the usual Nilsson model wave functions and the recently introduced proxy-SU(3) scheme.", "revisions": [ { "version": "v1", "updated": "2018-11-02T20:08:06.000Z" } ], "analyses": { "keywords": [ "shape coexistence", "usual nilsson model wave functions", "three-dimensional harmonic oscillator", "atomic nuclei", "lower deformations" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable" } } }
