Specifically, we have monitored the decay of the $|\\nu$=$1,J$=$1 \\rangle_X$ towards the $|\\nu$=$0,J$=$0 \\rangle_X$ level in MgH$^+$ by saturated laser excitation of the $|\\nu$=$0,J$=$2 \\rangle_X$-$|\\nu$=$1,J$=$1 \\rangle_X$ transition followed by state selective resonance enhanced two-photon dissociation out of the $|\\nu$=$0,J$=$2 \\rangle_X$ level. The technique enables the determination of decay rates, and thus abso"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1305.4087","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"}
