Development of a spectroscopy technique to measure local emission spectra of diatomic molecules by using the Zeeman effect

我们开发了一种利用外加磁场等离子体中的塞曼效应测量双原子分子局部发射光谱的光谱技术。为了发展这一技术，研究了两个课题：(1)建立在外加磁场作用下等离子体中双原子分子谱线形状的评价方法；(2)光谱技术在磁约束聚变实验装置中的应用。课题(1)按照研究计划的预期完成。对于主题(2)，我们测量了光谱，但由于缺乏波长分辨率，我们没有成功地解决塞曼效应的大小。另外，还计算了含氢同位素的双原子分子的反振动分子常数。

We have developed a spectroscopy technique to measure local emission spectra of diatomic molecules by using the Zeeman effect in plasmas with the external magnetic field. In order to develop this technique, two research topics were investigated :(1) Establishment of a method to evaluate the spectral line shapes of diatomic molecules in plasmas with the external magnetic field,(2) Application of the spectroscopy technique to a magnetic confinement fusion experimental device. Topic(1) was accomplished as expected in the research proposal. For topic(2), the spectra were measured, but we have not succeeded to resolve the magnitudes of the Zeeman effect because of the lack of the wavelength resolution. As an additional achievement, the ro-vibrational molecular constants of diatomic molecules which contains hydrogen isotopes were evaluated.
