We found that the N=20 shell closure in $^{28 \\sim 34}$Mg was broken by the prolate shape deformation originating from the {\\it fp}-intruder states. The shell closure breaking gives rise to a shift of low-lying GT excited states into high-lying states. Discussions regarding the shell evolution trend of single particle states around N=20 nuclei are also presented with the comparison to other approaches.","authors_text":"Eunja Ha, Myung-Ki Cheoun","cross_cats":["astro-ph.SR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-02-05T08:38:13Z","title":"Shell evolution of N=20 nuclei and Gamow-Teller strengths of $^{30,32,34}$Mg by the deformed QRPA"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1302.0959","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:bdfe35fc8a31f6a4d69e8f0161e09e58cf6f23488f1aa95be132685ef432b2c1","target":"record","created_at":"2026-05-18T03:20:09Z","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":"c28fce2ea46e00fb88502fd615e4e8057a4faf70e6f78022023e5400233b1be9","cross_cats_sorted":["astro-ph.SR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-02-05T08:38:13Z","title_canon_sha256":"09f46b7f1cc933a3f65182ec48df06d1f244e8d634f60efc1ce87265569b5abd"},"schema_version":"1.0","source":{"id":"1302.0959","kind":"arxiv","version":2}},"canonical_sha256":"2d71871d04ca8963c8d9dbe9065430ff5ddc77f5ca3d3b8a9550c42b09d1a702","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2d71871d04ca8963c8d9dbe9065430ff5ddc77f5ca3d3b8a9550c42b09d1a702","first_computed_at":"2026-05-18T03:20:09.284874Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:20:09.284874Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HUzuzXyxKNiyF1OUH3wIEgXrzQguC1gxzn1T/6Ug+PhAOlVdVtduMzlMa4RiUtucsUIcgB/FckxdD/8Wd2QODg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:20:09.285386Z","signed_message":"canonical_sha256_bytes"},"source_id":"1302.0959","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bdfe35fc8a31f6a4d69e8f0161e09e58cf6f23488f1aa95be132685ef432b2c1","sha256:9b8f404f7bf2e578922105d8ff96b9e00779b89ada67de049000304673da2511"],"state_sha256":"e8272e068ca5b495a1191b5c9aa21ce452947cd90385c28c58ad1f5d15a66be6"}
