摘要：

The reactions of Ba(1P1) with H2O and CO2 monomers and large clusters are compared. By cooling the H2O or CO2 beam with argon, one can eliminate all the monomers and produce a "pure" cluster beam. This allows one to compare the reactions of monomers and of clusters under clean conditions. While luminescence is observed from the reactive and inelastic collisions with the monomers, no emission is seen from the collisions with the clusters. The present observations support the idea that reaction with clusters results in the formation of a solvated product from which all visible luminescence is quenched.
