To this end, we perform a systematic theoretical analysis of non-fully-stretched I_max-2 and I_max-1 f_{7/2}^n seniority isomers and d_{3/2}^{-1} f_{7/2}^{n+1} intruder states in the A~44 nuclei from the lower-fp shell. We employ two theoretical approaches: (i) the density functional theory based on the cranked self-consistent Skyrme-Hartree-Fock method, and (ii) the nuclear shell model in the full sdfp configuration space allowing for 1p-1h cross-shell excitations. We emphasize the importance of restoration of broken angular momentum symmetry inherently obscuring the mean-field treatment of high-spin states. Overall good agreement with experimental data is obtained.", "revisions": [ { "version": "v1", "updated": "2007-01-09T12:38:48.000Z" } ], "analyses": { "subjects": [ "21.60.Cs", "21.60.Jz", "21.10.Pc", "21.10.Hw" ], "keywords": [ "shell model", "band termination", "mean-field description", "nuclear high-spin states undergoing", "angular momentum symmetry" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
