There is also evidence, both experimental and theoretical, that some actinide nuclei have barriers with a third minimum, outside the second, fission-isomeric minimum. We perform a large-scale, systematic calculation of actinide fission barriers to identify which actinide nuclei exhibit third minima. We find that only a relatively few nuclei accessible to experiment exhibit third minima in their barriers, approximately nuclei with proton number $Z$ in the range $88 \\leq Z \\le","authors_text":"Arnold J Sierk, Peter M\\\"oller, Takatoshi Ichikawa","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-03-01T02:32:41Z","title":"The character and prevalence of third minima in actinide fission barriers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1303.0067","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:deaeb2219517f8ad649eea77059114204d7cf5e877ebf34514971dc4c9423fcb","target":"record","created_at":"2026-05-18T01:51:25Z","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":"bbfa72759be9ff07c665039824e5921ecb5ca2c91d0c619629c4c1ccf74a0a4a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-03-01T02:32:41Z","title_canon_sha256":"17ea828958b40c2cb216a8e83d0fd3bf1c9e6829f4819027b7adfe539e7d4968"},"schema_version":"1.0","source":{"id":"1303.0067","kind":"arxiv","version":1}},"canonical_sha256":"9d3c29fed719e5f845f3bdae2cf1e512aabc6926043391f74ced237cfcb5c59f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9d3c29fed719e5f845f3bdae2cf1e512aabc6926043391f74ced237cfcb5c59f","first_computed_at":"2026-05-18T01:51:25.682209Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:51:25.682209Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"aqgtqCKqyeqCyDb3DtikEzR7XOd8gy1hnPfQmUX3R+CVw/ytNtgQgHp00amFWUvC1wEpQKgEarsgGo1FCfk7Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:51:25.682933Z","signed_message":"canonical_sha256_bytes"},"source_id":"1303.0067","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:deaeb2219517f8ad649eea77059114204d7cf5e877ebf34514971dc4c9423fcb","sha256:95522a05decad394d87d014f19c3ec2a8ca362e435e82bd4bee9a4e8beb82741"],"state_sha256":"641fed69520e07ed24f851678a5a73f83de964d459ac87c1e71230bbe1414084"}
