摘要：

An accurate adsorption calorimeter with good sensitivity to 0.01 ML of CO on Ni single crystals has been designed. Simultaneous measurements are obtained, using a pulsed molecular beam source, of differential heats of adsorption and of sticking probabilities as a function of surface coverage, theta. Results are presented for CO and O2 chemisorption and oxide film formation on Ni(100), and also for the separate interaction of CO and oxygen with various doses of preadsorbed K on Ni{100}.
