| Research Abstract |
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.
