-
摘要: 对Ag-与He原子碰撞的单电子脱附过程进行了实验研究,使用增长率方法在5~10keV能量范围内对脱附截面进行了测量,得到在20keV时的典型值为6.6×10-6 cm2。实验结果的不确定度约为8%。Abstract: The system and the method of the Ag- and He collision experiment are described, and the distinguishing feature of this experiment system is that only one detector was used. The single-elect rondetachment cross-sections of Ag- in collision with He has been measured in the energy range of 5~30keV by the growth-rate method. The typical value of the cross section of Ag- impacting on He at 20keV is 6.6×10-16cm2. The experimental uncertainty of the results is about ±8% in this work.
