Bestimmung der Gittkonstanten

m = 2; n = 2; 
    V = 253.9; ΔV = 6/V; θnm = 
      62.8 π/180;

a = 12.26*Sqrt[n^2 + m^2]/(Sqrt[V] Sin[θnm])

δa = Sqrt[(1.9/62.8)^2 + ΔV^2]

Δa = δa a

Bestimmung des Netzebenenabstandes

h = 6.626076 10^-34; me = 9.1093897 10^-31; 
    em = 1.602177 10^-19; θ = 90 π/180;

h/(Sqrt[8 me em] Sin[θ])
