Ar的第三谱带240nm中心谱区与气压关系的实验观察

Experimental Observation of the Dependence of 240 nm Central Spectral Region in the Third Continuum of Argon on Pressure

采用强流相对论电子束横向泵浦纯氩，获得了属于Ａｒ的第三谱带范围内２４０ｎｍ中心谱区的光强随气压变化的关系．结果表明，压强为３×１０５Ｐａ时是产生这一谱区的最佳气压。

Using high current relativistic electron beam to pump pure argon transversely, the dependence of 240 nm central spectral region in the third continuum of argon on pressure is observed, which indicates that 3105 Pa is the optimal pressure in producing this central spectral region, and proves that this central spectral region arises from the charged clusters.
