16. Explanation of Tables and Tabulated Figures

Form factors, attenuation and scattering cross-sections, Z = 1-92, from E = 0.001-0.010 keV to E = 400-1000 keV.
Z   Atomic number
E Photon energy in keV
λ Equivalent wavelength using E ·λ = 1.23984244 keV-nm, from Ref. [51]
Atomic weight g/mol, used in determination of conversion factors
ρ Nominal density in typical elemental material for users g/cm3
 µa Conversion for photoabsorption to barns/atom
Edge energies Values taken from Ref. [26]
Edge labels Spectroscopic notation (K=1s, LI=2s, LII=2p1/2, et seq.)
f1, f2 Atomic scattering factors in electrons/atom (or eu) for forward scattering using (eq 3-7) and (eq 8-18)
frel Relativistic correction to Re(f), following Ref. [6] (denoted H82), and Ref. [17-20] scaled as in Ref. [38,39] (denoted 3/5CL)
fNT Nuclear Thomson correction to Re(f) following (eq 4) and Ref. [13,14]
f2, K-shell Component of f2 relating to the isolated K-shell orbital
µ = µPE Photoabsorption cross-section in cm2/g
 µK Component of µ relating to the isolated K-shell orbital
σ(coh+inc) = σcoh+σinc Estimate of coherent and incoherent scattering cross-section sum
Attenuation coefficient 
= µ + σ(coh+inc)
Attenuation coefficient in cm2/gm
