摘要：

We have studied the chemical reactivity of the alkaline earth metal atoms Ba and Ca with N2O deposited on van der Waals (argon, nitrogen, methane, and neon clusters) in the case of Ba and on argon and helium clusters in the case of Ca. The first reaction forms BaO from 1 Ba and 1 N2O except at high Ba coverage where another channel is open yielding Ba2O. With Ca, the reaction 1:1 is hindered and the chemiluminescence comes from the reaction between 2 Ca and 2 N2O forming 2 CaO molecules.
