Traditionally, this rate involves the Coulomb logarithm, $\\ln\\Lambda$. Typical values of $\\ln\\Lambda$ are $\\approx 10~\\mbox{to}~20$ in kinetic theories where transport properties are dominated by weak-scattering events caused by long-range forces. The validity of these theories breaks down for strongly-coupled plasmas, when $\\ln\\Lambda$ is of order one. We present measurements and simulations of collision data in strongly-coupled plasmas when $\\ln\\Lambda$ is small.
