A clear signature of the dineutron correlation can be obtained by choosing the kinematical condition so the process via the $^5$He resonance is excluded because the $^5$He resonance dr","authors_text":"Kazuyuki Ogata, Masaki Sasano, Tomohiro Uesaka, Yuki Kubota, Yuma Kikuchi","cross_cats":["nucl-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2016-03-12T04:35:59Z","title":"Determination of a dineutron correlation in Borromean nuclei via a quasi-free knockout ($p,pn$) reaction?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1603.03858","kind":"arxiv","version":2},"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:a2d91d94ee6958e01e3f30743e3e47156fcbae9df5e1ee0772d79d3d05dd97e8","target":"record","created_at":"2026-05-18T01:05:43Z","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":"442bd0638ae4780635d5bebd68a444544551950596f64bfaf67469148819348d","cross_cats_sorted":["nucl-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2016-03-12T04:35:59Z","title_canon_sha256":"8f83add867ad69877f9e32740b19674441e2a1e0f069187f042dbda7f4f6c399"},"schema_version":"1.0","source":{"id":"1603.03858","kind":"arxiv","version":2}},"canonical_sha256":"2ca862395bdea6afb8677077e415120d2dbea7c84c13dc1454f3ce2a50cc4727","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2ca862395bdea6afb8677077e415120d2dbea7c84c13dc1454f3ce2a50cc4727","first_computed_at":"2026-05-18T01:05:43.791931Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:05:43.791931Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VP49E3RHp++hH24mPt+p9EOEJ/H+jiNpkBCXgM+3Wk0fzoCvs+d9JCVDWsVs8tjm+v98SGURbNAPKagQJLPACA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:05:43.792516Z","signed_message":"canonical_sha256_bytes"},"source_id":"1603.03858","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a2d91d94ee6958e01e3f30743e3e47156fcbae9df5e1ee0772d79d3d05dd97e8","sha256:065c5401de6971cfe6d904fa1e6fc72d8627aafe5a524e1e2d2b2a2b32bdb553"],"state_sha256":"73c550c6ea459278d1f2ee8186a484a51a43a6a4015ec874b5eb826483efb84c"}
