摘要

在2×1.7串列加速器上

利用装有CCD的Spectrapro-500i光谱单色仪的测量装置

采用束-箔方法

在2 MeV束能下研究350-450 nm波长范围的离化态氧原子光谱。本文报道在350-450 nm范围已确定的182条光谱线

这些谱线大都属于O II到O IV原子的n、1能级间的跃迁的弱谱线。实验结果与现有的一些理论一致。实验发现

有28条谱线在以前的文献中没有报道。

Abstract

Spectra of the ionized oxygen atoms were studied by pro-500i monochromator equipped with CCD.The beam foil method was used with 2 MeV oxygen ion beams.In this paper

we report 182 spectral lines determined in the 350-450 nm region.Most of the spectral lines were attributed to n

1 energy level transitions from OII to OIV atoms.The experimental results are in good agreement with available theoretical results.The 28 lines were found for the first time

and a majority of the spectral lines attribute to week transitional lines.
