The ac electrical conductivity of a dense plasma is studied by use of reflectivity measurements on the rear surface of a laser-irradiated planar target. The results show general agreement with theory in which a minimum collision mean free path is assumed, yielding correspondingly a minimum conductivity. However, the results also suggest that the minimum mean free path is greater than the interatomic radius.
