We discuss two bands of $^{25}_{\\ \\Lambda}$Mg corresponding to the $K^\\pi=0^+$ and $2^+$ bands of $^{24}$Mg. It is found that the energy of the $K^\\pi = 2^+ \\otimes \\Lambda_s$ band is shifted up by about 200 keV compared to $^{24}$Mg. This is because the $\\Lambda$ hyperon in $s$ orbit reduces the quadrupole deformation of the $K^\\pi = 0^+ \\otimes \\Lambda_s$ band, while it does not change the deformation of the $K^\\pi = 2^+ \\otimes \\"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1109.1116","kind":"arxiv","version":2},"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"}
