[en] The quenching of XeF(B) was studied by using the steady-state photolysis of XeF₂ as the source of XeF(B). The XeF(C) state was observed, as well as the XeF(B) state, by using a very clean CO(A-X) resonance lamp to photolyze the XeF₂. XeF(C) must be included in the kinetic scheme in order to understand the quenching of XeF*. The preliminary work that has been done with the Xe(³P₁) and Kr(³P₁) resonance atom reactions is summarized. The pulsed laser induced fluorescence technique was used to measure radiative lifetimes and two-body quenching rate constants. The study of Ne(3p)** in Ne Buffer has been completed and tables of these results are included. Some exploratory work searching for new emission spectra and with an emphasis on rare gas oxide spectra has been done and is described
