Scherrer at (K, λ, β, θ) = (1, π, π, 0): t = 1 (unit crystallite-size canonical)

Sympy-exact witness of the Scherrer crystallite-size relation at a clean unit-parameter point. Setup: K=1 (dimensionless shape factor), λ=π (arbitrary wavelength scale), β=π (FWHM same order), θ=0 (peak at zero-angle limit). Canonical…
