Abstract
Chemiluminescent reactions of samarium with bromine-containing hydrocarbons are reported under atomic beam-gas conditions. The chemiluminescent emission is in the visible region and is attributed to SmBr2 emitter. The scattering and chemiluminescent cross-sections and photon yields are determined and compared with corresponding chloro analogues. The photon yields for the emitters are found to be in the order: SmBrCl > SmBr2 > SmCl2. The total cross-sections are estimated from the known polarizabilities of the reactants using the Massey-Mohr expression and are compared with those observed. The fraction of the total exoergicity appearing as product electronic excitation is estimated and is found to be about 0.1%.
