摘要/Abstract

摘要： 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,并证实了这一谱区是由带电的原子团簇产生的.

Abstract: 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 3×10⁵Pa is the optimal pressure in producing this central spectral region, and proves that this central spectral region arises from the charged clusters.
