Effect of Pd impurity on charge and spin density in metallic iron ...

2 σ + 3 parameters at most provided the concentration <strong>of</strong> impurities c is treated as variable.
Otherwise the maximum number <strong>of</strong> variables describing distribution equals 2 ( σ + 1)
.
Figure 2.
Hyperfine field and relative spectral shift plotted versus palladium concentration. Straight
lines are the lowest order approximations to the trends observed, particularly for shifts.
