Measurements of correlations enhanced collision rates in the mildly correlated regime (Γ~1)
Abstract
We measure the perpendicular-to-parallel collision rate ν⊥|| in laser cooled, magnetized ion plasmas in the mildly correlated regime of Γ~1 and find collision rates enhanced by exp(Γ). This ν⊥|| enhancement due to correlations is directly analogous to the enhancement of fusion collisions in hot dense stellar plasmas, as first analyzed by Salpeter [Aust. J. Phys. 7, 373 (1954)]. The enhancement is caused by screening of the repulsive Coulomb potential between charges, allowing closer collisions for a given relative energy. The measurements indicate that the screening is done by thermal particles and allows us to rule out dynamical screening theories, which predict no enhancement to the collisions rate for Γ≲ 1.
