This new ab initio method, no-core shell model with continuum (NCSMC), leads to convergence properties superior to either NCSM or NCSM/RGM while providing a balanced approach to different classes of states. In the NCSMC, the ansatz for the many-nucleon wave function includes: i) a square-integrable A-nucleon component expanded in a complete harmonic","authors_text":"Petr Navratil, Simone Baroni, Sofia Quaglioni","cross_cats":["quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-01-15T18:45:52Z","title":"Unified ab initio approach to bound and unbound states: no-core shell model with continuum and its application to 7He"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1301.3450","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9428d71a7697771e2b6527c65b6d213419767c75a0dd7faa154a55f3d813f1e0","target":"record","created_at":"2026-05-18T03:29:15Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c7d9253a3d712a3722e54c6da869e07787ea952943a78aa13395a0b4332c6287","cross_cats_sorted":["quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-01-15T18:45:52Z","title_canon_sha256":"8e957d12cce8768a8ddd6d63be01556be3577735adc74bb86ec9d38e0de90b9d"},"schema_version":"1.0","source":{"id":"1301.3450","kind":"arxiv","version":1}},"canonical_sha256":"0884ae31c6ad2d5dce3c9c3d484d46135bf77f3f90bc335a5bdc30622acaf2cf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0884ae31c6ad2d5dce3c9c3d484d46135bf77f3f90bc335a5bdc30622acaf2cf","first_computed_at":"2026-05-18T03:29:15.659349Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:29:15.659349Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"vulwLZbeIusOSh3KGsBE1TiP8MuvkbTNxTSDLBWpjgqYxZgepy0UgOq21WyNgBFFTMEpWazJdUonpZF9xgkjBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:29:15.660190Z","signed_message":"canonical_sha256_bytes"},"source_id":"1301.3450","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9428d71a7697771e2b6527c65b6d213419767c75a0dd7faa154a55f3d813f1e0","sha256:f7e62e172a8a69a957c1c12f3088f94035a6d3a2d2e162f64ecb68027557c81a"],"state_sha256":"c16a2e9fe387ec8532e1aa53cd066576d98ef300f8f6880243349f2942c6e7c2"}
