Although macroscopic approaches offer useful insights, microscopic analyses of high-precision experimental data provide a more reliable framework for understanding the nucleon transfer mechanisms. The present study aims to carry out a comprehensive theoretical investigation of the $^{116}$Sn+$^{60}$Ni system using microscopic coupled reaction channel (CRC) calculations. The calculations employ microscopic double-folding S$\\tilde{a}$o Paulo potentials, incorporating all releva"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"This study highlights that microscopic description of one- and two-nucleon transfer between two heavy ions in the CRC framework, without taking recourse to arbitrary normalization of the cross sections, is quite feasible.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"All relevant inelastic and transfer couplings are included in the CRC calculations guided by observed γ-ray transitions, wherever available, and that the shell-model spectroscopic amplitudes remain accurate despite computational limits on the number of states.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Microscopic CRC analysis of 116Sn+60Ni reproduces quasielastic and 1n transfer data well, with the extreme cluster mechanism best describing two-nucleon transfer.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Microscopic coupled reaction channel calculations reproduce one- and two-nucleon transfer data in the 116Sn + 60Ni system without arbitrary normalization of cross sections.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"54ee12955bf32210127ff86b48527f063fe623d0b44261145eaa395e42f522cd"},"source":{"id":"2605.16533","kind":"arxiv","version":1},"verdict":{"id":"10f7bca1-f711-4b38-97a0-d4e2e17ecdd7","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-19T21:30:01.520069Z","strongest_claim":"This study highlights that microscopic description of one- and two-nucleon transfer between two heavy ions in the CRC framework, without taking recourse to arbitrary normalization of the cross sections, is quite feasible.","one_line_summary":"Microscopic CRC analysis of 116Sn+60Ni reproduces quasielastic and 1n transfer data well, with the extreme cluster mechanism best describing two-nucleon transfer.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"All relevant inelastic and transfer couplings are included in the CRC calculations guided by observed γ-ray transitions, wherever available, and that the shell-model spectroscopic amplitudes remain accurate despite computational limits on the number of states.","pith_extraction_headline":"Microscopic coupled reaction channel calculations reproduce one- and two-nucleon transfer data in the 116Sn + 60Ni system without arbitrary normalization of cross sections."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2605.16533/integrity.json","findings":[],"available":true,"detectors_run":[{"name":"doi_title_agreement","ran_at":"2026-05-19T22:01:23.130425Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"doi_compliance","ran_at":"2026-05-19T21:41:16.940708Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"ai_meta_artifact","ran_at":"2026-05-19T19:33:23.070952Z","status":"skipped","version":"1.0.0","findings_count":0},{"name":"claim_evidence","ran_at":"2026-05-19T19:21:56.928709Z","status":"completed","version":"1.0.0","findings_count":0}],"snapshot_sha256":"d286a293dcef5bbfe56954e6a800a842d8f313c10270f32915e70419640b2008"},"references":{"count":69,"sample":[{"doi":"","year":null,"title":"Here two routes for neutron transfer are illustrated: (i) the direct route (denoted by (blue) dash- dotted line) in which the constituents of the entrance channel is in the ground state and (ii) the i","work_id":"7993f568-af6c-418a-b484-3916b2a02300","ref_index":1,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":null,"title":"The coherent sum of the angular distri- butions were determined by the interference between the direct and the indirect paths","work_id":"02834241-69d9-488d-9403-815df2a9bdc3","ref_index":2,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2019,"title":"in the CRC calculations by including additional states for which γ-transitions were identified [ 36].
