Abstract
The radiolysis of ethane has been studied over the density range 0.0018–0.5 g cc−1 at a temperature just above the critical point. The variations of product yields with increasing density are consistent with increasing collisional stabilization of excited species. Electron scavenging by sulfurhexafluoride in ethane at 0.275 g cc−1 is accurately described by an expression used for liquid phase scavenging with Gfree ions = 0.65. At 0.052 g cc−1 a much higher yield of free ions is observed and at high sulfurhexafluoride concentrations there is a sensitized decomposition of ethane.Ammonia-d3 scavenges ions at all densities but in the region around 0.07 g cc−1 a mechanism operates which produces more than one hydrogen molecule per ion scavenged. The freely diffusing ions do not appear to be readily scavenged by ammonia-d3.
