Abstract

This paper considers the relaxation processes in stepwise electron/laser excitations that are affected by radiation trapping. The pressure dependence of the observed linear and circular polarisations is examined and quantified. An extrapolation to zero pressure is found to be significantly different from a linear fitting procedure. This enables the extraction of true values of the state multipoles, which describe the alignment and orientation of the mercury 6(1)P(1) state immediately after electron-impact excitation.
