Interpretation: Bragg's wavelength for the palladium line was 1.7 per cent low (0.576 against 0.5859 angstrom), so a spacing computed from it is expected to be about 1-2 per cent high; the two per cent threshold is set to the claimed number, not corrected for the wavelength. The correction is reported alongside. https://w3id.org/delphi/resource/assessment/bragg1915-06--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of bragg1915-06: supports, confidence 0.85 https://w3id.org/delphi/resource/assessment/bragg1915-06--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/crystals-and-form/bragg1915-06/result.json https://w3id.org/delphi/resource/assessment/bragg1915-06--claim-test http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-claude-fable-5-1 https://w3id.org/delphi/resource/assessment/bragg1915-06--claim-test https://w3id.org/delphi/ontology/admissibleDatasets Planned datasets: cod-search-api https://w3id.org/delphi/resource/assessment/bragg1915-06--claim-test https://w3id.org/delphi/ontology/assessmentType claim-test/0.1.0 https://w3id.org/delphi/resource/assessment/bragg1915-06--claim-test https://w3id.org/delphi/ontology/dataKind physical https://w3id.org/delphi/resource/assessment/bragg1915-06--claim-test https://w3id.org/delphi/ontology/disconfirmingObservation Relative difference above 0.05: refutes.
