Molecular beam chemiluminescence studies of the systems SmSF6 and SmCCl4
The beam gas chemiluminescence reactions of samarium with SF6 and samarium with CCl4 have been studied. The emission is attributed to SmF2* and SmCl2* emitters. The reactions are first order with respect to both metal and oxidizer gas at low pressures. The total cross-section, chemiluminescence cross-section and photon yields for the reactions have been found to be 280 Å2, 0.44 Å2 and 0.0015 respectively for the samarium plus SF6 reaction and 315 Å2, 0.32 Å2 and 0.001 for the samarium plus CCl4 reaction.
