Measurement of correlation-enhanced collision rates.
We measure the perpendicular-to-parallel collision rate nu perpendicular parallel in laser-cooled magnetized ion plasmas, spanning the uncorrelated to correlated regimes. In correlated regimes, we measure collision rates consistent with the "Salpeter correlation enhancement" of roughly exp(Gamma), for correlation parameters Gamma less, similar 4. This enhancement also applies to fusion in dense plasmas such as stars.
