A King Plot is drawn resulting in an updated value for the specific mass shift $\\delta \\nu_\\mathrm{684,sms}^\\mathrm{164-162}=-534 \\pm 17 MHz$. Using fluorescence spectroscopy we measure the excited state lifetime $\\tau_{684}=1.68(5) \\mu$s, yielding a linewidth of $\\gamma_\\mathrm{684} = 95 \\pm 3 kHz$. We give an upper limit to the branching ratio between the two decay channels from the excited state showing that this transition "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1301.3645","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
