Abstract

The x-ray scattering from

{Fe}_{3}

Al corresponds closely to a pair correlation function,

\frac{\exp (- κ r)}{r^{1 + η}}

, with

η = 0.080 \pm 0.005

, for temperatures from

2 \times 10^{- 4} T_{c}

to

2.5 \times 10^{- 2} T_{c}

above the critical ordering temperature

T_{c}

. The inverse length,

κ

, is proportional to

{(T - T_{c})}^{ν}

, with

ν = 0.649 \pm 0.005

.
