The states of two valence neutrons are classified based on the molecular-orbit (MO) model, and the $\\pi$-orbit is introduced about the axis connecting the two $\\alpha$-clusters for the description of the rotational bands. There appear two rotational bands comprised mainly of $K^\\pi = 0^+$ and $K^\\pi = 2^+$, respectively, at low excitation energy, where the two valence neutrons occupy $K^\\pi = 3/2^-$ or $K^\\pi = 1/2^-$ orbits. The triaxiality and the $K$-mixing are discussed in connection to the"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"nucl-th/0109039","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"}
