For a $\\Lambda$ in the $1s$ and $1p$ states in $^{17}_{\\Lambda}$O, $^{41}_{\\Lambda}$Ca, $^{49}_{\\Lambda}$Ca, $^{91}_{\\Lambda}$Zr, and $^{209}_{\\Lambda}$Pb, we compare the single-particle energies and density distributions of the core nucleons with those of the nuclei without the $\\Lambda$, as well as the point proton and neutron radii. A remarkable finding is that the bound $\\Lambda$ induces a significant asymmetry in th"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1203.0465","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"}
