To provide a more rigorous treatment, we propose an approach which incorporates the full interdependence between nuclear structure and lepton kinematics. Deviations of the decay rates and electron spectra from the traditional methods, such as closure, non-closure and Taylor expansion approximation, are presented and discussed for the isotopes $^{82}$Se and $^{136}$Xe. Our approach gives a more realistic description of the DBD process, and opens the a","authors_text":"Andrei Neacsu, Sabin Stoica, Stefan-Alexandru Ghinescu","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"nucl-th","submitted_at":"2026-06-30T04:04:04Z","title":"Exact Calculation of Two-neutrino Double Beta Decay Rate"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.31107","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":"sha256:8ba7e4ceb4ce6c72b0336d46d7e347ae2ec46cbaefe8cdd173628558f44a8e18","target":"record","created_at":"2026-07-01T01:17:29Z","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":"c34d628f195962957d8a028da47ae2a0e0e7adfb229530a0b0cda1f5294913d5","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"nucl-th","submitted_at":"2026-06-30T04:04:04Z","title_canon_sha256":"1b2979f705c83ff4d1c64143784eed4322ae633ed7b8f4dca002499862bada93"},"schema_version":"1.0","source":{"id":"2606.31107","kind":"arxiv","version":1}},"canonical_sha256":"44f7759f3c470fd7fd6618be89dd28622ce51ca7b0dc9bf4d1b23f2d7a5272a6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"44f7759f3c470fd7fd6618be89dd28622ce51ca7b0dc9bf4d1b23f2d7a5272a6","first_computed_at":"2026-07-01T01:17:29.374300Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-01T01:17:29.374300Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"clGdfHLkgutN8mUvQ4A5eqAXwl5OQZwcnC3g6cS/UsKsgc5AmGYzK/2nVNDm0EsROjf+LnsGY2b143jsEFWDDQ==","signature_status":"signed_v1","signed_at":"2026-07-01T01:17:29.374718Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.31107","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8ba7e4ceb4ce6c72b0336d46d7e347ae2ec46cbaefe8cdd173628558f44a8e18","sha256:ddec7f4abf51d74d03570e68bae465161217ebba85a5c2dda1c33c4e146a27ee"],"state_sha256":"1ea5e99cb8e049a9097fe6d8727295ff5f50ed2e1a667a43d1292504066c5876"}
