The $^6$Li($p, \\gamma$)$^7$Be reaction can provide us not only the information for destroying $^6$Li but also the information for producing $^7$Be. In the present work, the proton spectroscopic factor in $^7$Be was extracted to be 0.70 $\\pm$ 0.17 from the angular distribution of $^7$Be($d$, $^3$He)$^6$Li at $E_\\mathrm{c.m.}$ = 6.7 MeV. The value was then used to compute the direct component of the astrophysical $^6$Li($p, \\gamma$)$^7$Be$_\\mathrm{g.s.}$ S(E) factors and determine the "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.10946","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
