In this improved interaction, the momentum-dependence of the isoscalar single-particle potential at saturation density is well fitted to that extracted from optical model analyses of proton-nucleus scattering data up to nucleon kinetic energy of 1 GeV, and the isovector properties, i.e","authors_text":"Bao-An Li, Jun Xu, Lie-Wen Chen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2014-10-07T03:07:16Z","title":"Thermal properties of asymmetric nuclear matter with an improved isospin- and momentum-dependent interaction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1410.1604","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:d6273dd507c14f3a6f4233bc868be9ff40f8722793beaf66785eb9104ac15b8a","target":"record","created_at":"2026-05-18T02:28:54Z","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":"75ac43d0eb4636cc97b213d068a2b30234c5d485977d0ed58801243741a9cdab","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2014-10-07T03:07:16Z","title_canon_sha256":"1e93d74792f89f53a5c194d2f854e7ab67927178d8938764ec87774cd8b2967e"},"schema_version":"1.0","source":{"id":"1410.1604","kind":"arxiv","version":2}},"canonical_sha256":"afa27c72f935c644c8400b270982a4397c8ee59cf498bc67a8ea821bd50beebe","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"afa27c72f935c644c8400b270982a4397c8ee59cf498bc67a8ea821bd50beebe","first_computed_at":"2026-05-18T02:28:54.986288Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:28:54.986288Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"LXau7V0dZ7HDExiY9WfGX+usDyVpcBOdelzqg9Dz7LV01ekBd+hjDfty8sDEX/9waZF7hrDt/x7/2wT1gnjrCw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:28:54.986693Z","signed_message":"canonical_sha256_bytes"},"source_id":"1410.1604","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d6273dd507c14f3a6f4233bc868be9ff40f8722793beaf66785eb9104ac15b8a","sha256:c7028fdb7ae627b5271d265bcb8f1c36fa0ac188538a74d37b30ef1d6998af39"],"state_sha256":"cb6529b36690f0e386d49719b6bdf182b39c0dbada0a62e6b43078373b88d622"}
