Determination of the relative photodetachment cross sections of the two isomers of (H 2O) 6− using saturated photodetachment

Abstract

We report relative photodetachment cross sections for the two isomers of (H 2O) 6 − at 1.165 eV by monitoring the photoelectron spectrum as a function of laser fluence. The cross sections of the two isomers differ by only about a factor of three, much closer to each other than suggested by recent calculations by Kim et al.
