The recent experimental measurements reveal that the fusion-evaporation cross section in the $3n$ reaction channel of $^{48}$Ca+$^{239}$Pu is 50 times lower than using $^{244}$Pu as target nucleus. However, the precise mechanisms of this remarkable isotopic dependence are not well understood.\n  Purpose: To understand the experimental observation of the rapid decrease of stability of superheavy nuclei as the neutron number decreases, the theoretical studies of quasifission and fu","authors_text":"Caiwan Shen, Chong Yu, Lu Guo, Zhenji Wu","cross_cats":["nucl-ex"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"nucl-th","submitted_at":"2018-10-31T05:36:11Z","title":"Isotopic trends of quasifission and fusion-fission in the reactions $^{48}$Ca+$^{239,244}$Pu"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.13114","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":"sha256:61e9321ae067c8615531259fcbd7243d79312599e5054f16ce4700c7c29845d7","target":"record","created_at":"2026-05-17T23:56:45Z","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":"33b19e1f1ddf5d59b9defc61be55c99ac4bf35a94de3dd93c59f1e47fb64f066","cross_cats_sorted":["nucl-ex"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"nucl-th","submitted_at":"2018-10-31T05:36:11Z","title_canon_sha256":"8b5be1401ab3a31118deee84ad862baf3f8c6a92d67ee5635e293a0ba8887186"},"schema_version":"1.0","source":{"id":"1810.13114","kind":"arxiv","version":1}},"canonical_sha256":"a9cc475c8b8ea00bfafc150a1ca3221b8a9c24cef7a6775e24b970cfc922918d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a9cc475c8b8ea00bfafc150a1ca3221b8a9c24cef7a6775e24b970cfc922918d","first_computed_at":"2026-05-17T23:56:45.169869Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:56:45.169869Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"sWfPbFVHvyidESYlTaEChuI/iBJbYVII+bk+mmyXgD5N34EZxKdS83rzJ7L28ZJs3oOc6MP3Rm0OCkQkGlO3Cg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:56:45.170249Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.13114","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:61e9321ae067c8615531259fcbd7243d79312599e5054f16ce4700c7c29845d7","sha256:28b2bf1b36cedbc5706b31f2adf8a742140a4081015e1ff42b25c792044908a2"],"state_sha256":"ce293422c91abab2bb0debb1a6a4812e227db6cad6fa4deea69e288a0746b52d"}
