Steric control of molecular beam induced surface reactions and its ultra-high speed and high energy resolution photoemission spectroscopic analysis

为了克服束流密度不足的问题，研制了一种连续膨胀型超音速分子束源及相关器件。通过对等离子体离子源的改造，提高了高速原子分子(离子)束装置的离子电流。改进了光电发射光谱的高速测量，将测量系统更换为与5通道探测器相对应的新系统。利用最新研制的实验装置，用高速光电子能谱研究了多种分子束诱导表面反应的各种表面反应机理。

A continuous expansion type supersonic molecular beam source and related devices were fabricated to overwhelm insufficient beam flux density. Ion current of a high speed atomic and molecular (ion) beam apparatus was enhanced by reconstruction of the plasma ion source. High speed measurements of photoemission spectra were improved by replacing a measurement system to new one which is corresponding to a 5 channels detector. Various kinds of surface reaction mechanisms of many molecular beam induced surface reactions were clarified by high speed photoemission spectroscopy using newly developed experimental devices.
