Systematic measurements were carried out for six samples with different size and surface roughness. The power-law behavior, $\\Delta \\lambda(T) = A T^n$ was found for all samples with the average exponent $n_{avg} = 2.3 \\pm 0.1$ and the pre-factor $A_{avg} = 1.0 \\pm 0.2$ nm/K$^{2.3}$. The average superfluid density is well described by the self-consistent two-gap $\\gamma$ model resulting in $\\Delta_{_{I}}(0)/k_B"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1107.0711","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"}
