 Table 3. List of elemental solids with values of Z or Z – 1.65 (see text), Zeff from Eq. (5)], errors in the f-sum rule, values of Peff from Eq. (6), and errors in the KK-sum rule. Values of Zeff and Peff were determined with = 30 keV. ____________________________________________________________________________________________________________________           Element            Z or Z – 1.65       Zeff              Error in f-sum rule (%)             Peff   Error in KK-sum rule (%) Li 3 3.06 2.1 1.018 1.8 Be 4 4.09 2.4 1.066 6.6 C (graphite) 6 6.29 4.8 1.077 7.7 C (diamond) 6 5.97 -0.5 0.998 -0.2 C (glassy) 6 5.77 -3.9 0.998 -0.2 Na 11 11.13 1.2 1.035 3.5 Mg 12 13.28 10.6 0.974 -2.6 Al 13 13.12 0.9 1.017 1.7 Si 14 14.10 0.7 0.959 -4.1 K 19 17.72 -6.8 0.840 -16.0 Sc 21 22.90 9.0 0.925 -7.5 Ti 22 21.90 -0.5 1.023 2.3 V 23 22.81 -0.8 1.013 1.3 Cr 24 22.30 -7.1 1.059 5.9 Fe 26 23.90 -8.1 1.068 6.8 Co 27 26.55 -1.7 1.012 1.2 Ni 28 27.32 -2.4 1.065 6.5 Cu 29 28.55 -1.5 0.996 -0.4 Ge 32 32.65 2.0 1.042 4.2 Y 39 37.76 -3.2 0.902 -9.8 Nb 41 37.90 -7.6 0.854 -14.6 Mo 42 39.53 -5.9 0.989 -1.1 Ru 44 41.43 -5.9 1.092 9.2 Rh 45 44.11 -2.0 1.126 12.6 Pd 46 44.94 -2.3 1.126 12.6 Ag 47 49.97 6.3 1.005 0.5 In 49 47.25 -3.6 0.917 -8.3 Sn 48.35 48.64 0.6 0.769 -23.1 Cs 53.35 49.33 -7.5 1.004 0.4   36/60
