Converting polarizability from cgs to MKS
α(F-m²) = 4e-6 π ε₀ α(cm³) ... https://en.wikipedia.org/wiki/Polarizability#Definition
Computing MKS Cross Section
ω = 2 π c / λ
σ(m²) = ω⁴ α(F-m²)² /( 12 π ε₀² c⁴ )
- = ω⁴ 16e-12 π² ε₀² α(cm³)² / ( 12 π ε₀² c⁴ )
- = ω⁴ 4e-12 π α(cm³)² / ( 3 c⁴ )
- = 64e-12 π⁵ α(cm³)² / ( 3 λ⁴ )
- = 64e24 π⁵ α(cm³)² / ( 3 λ(nm)⁴ )
Define β = 64e24 π⁵ α(cm³)² / 3 = 6.52842e27 α(cm³)²
- β = 6.52842e-3 (nm⁶) (table value)²
σ(nm²) = β / λ(nm)⁴
.... ok, something's wrong, the numbers are WAY too small
