    "abstract": "Inspired by recent experiments on fully spin polarized Na clusters, we\nperform a systematic survey of neutral Na clusters at all conceivable spin\npolarizations. We study the impact of spin state on ionic configuration, on\nglobal shape, and on optical response. For small clusters, the magic electronic\nshell at 4 spin-up electrons is a dominating feature leading to preferred\nbinding for all clusters having four spin-up electrons (combined with 1 to 4\nspin-down electrons). Such a preference fades away for larger systems where the\nunpolarized state is generally preferred.",
