Figure 50: Smoothing parameter λ dependent HFD (right) extracted from 80 K Mössbauer spectrum (left) for small Fe particles ( 𝐻 o i = 31.47 T, l = 0.31 mm s−1, = 0.15 T). (a) 𝜆 = 0 (HR = 2.085, 𝜒 2 = 2.727); (b) 𝜆 = 10−3 (HR = 2.088, ( 𝜒 2 = 2.731); (c) 𝜆 = 10−2 (HR = 2.092, 𝜒 2 = 2.736); (d) 𝜆 = 0.05 (HR = 2.095, 𝜒 2 = 2.740).
