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.

我们开发了一种光谱技术，通过利用等离子体中的塞曼效应和外部磁场来测量双原子分子的局部发射光谱。为了发展这项技术，研究了两个研究课题：（1）建立一种评估外部磁场下等离子体中双原子分子谱线形状的方法，（2）光谱技术在磁约束聚变中的应用实验装置。主题（1）已按研究计划中的预期完成。对于主题（2），测量了光谱，但由于缺乏波长分辨率，我们尚未成功解决塞曼效应的大小。作为另一项成就，评估了含有氢同位素的双原子分子的旋转振动分子常数。
