Derived Parameter: Spitzer Conductivity

Spitzer Conductivity

BLURB

$\eta_\parallel =\frac{T^{3/2}}{7.3\times 10^{-9}Z\ln \Lambda } \ \ \mathrm{s^{-1}}$
$\eta _\perp =3.3\eta _\parallel$

where T is in Kelvins, and

$\ln \Lambda=23.5 - \ln \left (1.2046 \times 10^5 \frac{\sqrt{n_e} }{T^{1.25}} \right ) - \sqrt{10^{-5} + \frac{\left ( \ln(T) - 11.35926 \right )^2}{16}$
