Determination of a complete set of parameters (λ,χ,Δ and ε) incorporating spin-orbit effects from an electron-photon coincidence experiment on the excitation of the 63P1state of mercury by electron impact

Abstract
Linear and circular polarisation measurements have been carried out for photons from the 63P1-61S0 transition in mercury, which were detected in delayed coincidence with electrons having excited the 63P1 state. These measurements have been used to determine values for the parameters lambda , chi and the spin-orbit phase angles Delta and epsilon for the 61S0 to 63P1 to 61S0 excitation/de-excitation process in mercury.
