(1)Sample-preparation system for ARUPS of organic self-assembled monolayer's (SAMs) was constructedat the beam line 4A of CAMO.Using this system, ARUPS of pyrrolyl-SAM's prepared on Au and Ag substrates were in situ mneasured for the first time.(2)The photoelectron angular distributions from various thin films prepared by organic molecular beam epitaxy were successfully analyzed, and quantitative molecular orientation and origin of spectral bands were determined.(3)ARUPS combined with The above analysis method was applied to investigate' geometrical structure and chemical reactions of polymer surfaces which could not be investigated by UPS.It was found that the quantitative analysis of the photoelectron intensity is possible even for such conplicated organic system, and surface molecular orientation was determined for thin films of pendant-group polymers.

（1）在CAMO的4A光束线上建立了有机自组装单分子膜（SAMs）的ARUPS样品制备系统，利用该系统首次对在Au和Ag衬底上制备的吡咯基自组装单分子膜的ARUPS进行了原位测量。（2）成功地分析了各种有机分子束外延薄膜的光电子角分布，确定了光谱带的定量分子取向和来源。（3）ARUPS结合上述分析方法研究了UPS无法研究的聚合物表面的几何结构和化学反应，发现即使对于这样复杂的有机体系，光电子强度的定量分析也是可能的，并确定了侧基聚合物薄膜的表面分子取向。
