In a study with random interactions it is shown that the appearance of regular spectral features is a far more common phenomenon than was previously thought. The origin of these features are explained by studying the relation with the underlying geometric shapes.","authors_text":"Roelof Bijker","cross_cats":[],"headline":"","license":"","primary_cat":"nucl-th","submitted_at":"2004-12-17T17:22:51Z","title":"Shape-phase transitions in nuclei and random interactions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"nucl-th/0412069","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":"sha256:3ab2d30b2d20711f5c74be094afb04e40eec38354126f39f3b40ab76cd1e4bd0","target":"record","created_at":"2026-05-18T00:31:31Z","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":"8d4db42a1afda8fa8ea9c1957ff0e8aedd6a41a6e92edd072668a224260167c7","cross_cats_sorted":[],"license":"","primary_cat":"nucl-th","submitted_at":"2004-12-17T17:22:51Z","title_canon_sha256":"07de0f5a730688c8793a8a04cd7cde3d3d0d23e0e6c4701abc07bbfb96544758"},"schema_version":"1.0","source":{"id":"nucl-th/0412069","kind":"arxiv","version":1}},"canonical_sha256":"7cd05d1c9edfc69abd5bfe4f5ef892b390e52e64fa0fd9c07f85b17dfb88a15e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7cd05d1c9edfc69abd5bfe4f5ef892b390e52e64fa0fd9c07f85b17dfb88a15e","first_computed_at":"2026-05-18T00:31:31.961457Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:31:31.961457Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jvNI/chTBJeGMZDQJQ5x2gaI9grXphDY/ZgQgftymR4KaOariSoWIfdR/SYwordfROjWgUMB0wx1+x76X/utAg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:31:31.962104Z","signed_message":"canonical_sha256_bytes"},"source_id":"nucl-th/0412069","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3ab2d30b2d20711f5c74be094afb04e40eec38354126f39f3b40ab76cd1e4bd0","sha256:ff5e8432e499b3f6ac84f14a72658802b89774724141bc3c24cf20796b33cc7b"],"state_sha256":"b518084abbf4b801fc767732f26b196523eaaea6cda47094f1c47a1af2243b58"}
