Characteristic X-ray spectral linewidths in NIST reference data (ΔE/E ~ 10^-4 to 10^-3, corresponding to wave trains of thousands of oscillations) and sharp Bragg reflection profiles directly confirm Bragg's deduction over the rival irregular-pulse hypothesis. https://w3id.org/delphi/resource/assessment/bragg1913r-02--gemini http://purl.org/dc/terms/subject https://w3id.org/delphi/resource/concept/dataset-resolvability-0.2.0 https://w3id.org/delphi/resource/assessment/bragg1913r-02--gemini http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/LLMClaimAssessment https://w3id.org/delphi/resource/assessment/bragg1913r-02--gemini http://www.w3.org/2000/01/rdf-schema#comment Proposed test with existing data: Measure the angular full-width at half-maximum (Δθ) of characteristic X-ray Bragg reflections from high-perfection single crystals (and compare with the natural spectral linewidth Δλ/λ of characteristic atomic emission lines). Using diffraction grating / Scherrer / Darwin dynamical diffraction theory, compute the minimum longitudinal coherence length L_c = λ^2 / (2 Δλ) (or number of interfering wave trains N = λ / Δλ) required to produce the observed angular sharpness, and confirm that N >> 1 (on the order of 10^3–10^4 wavelengths), refuting single unorganized impulses.
